2 The LPR®-1DHP-200 Product Family
The LPR®-1DHP-200 is a radar distance measurement sensor product family. The product
family consists of different product types, which are based on the same hardware platform.
Depending on your purchased product type, your radar provides one or more of three
different radar modes, namely a primary radar mode, a secondary radar mode and a
diversity radar mode. Table 2.1 shows the different product types and their supported radar
modes.
LPR®-1DHP- 220-R 260 281 290
Table 2.1: Supported radar modes for different LPR®-1DHP-200 product types.
Typical applications of the LPR®-1DHP-200 are:
Positioning of cranes, crane trolleys, hoists and other railbound transport systems
Process automation, monitoring and control
Collision avoidance
While reading this document keep in mind which radar modes are
supported by your device.
All LPR®-1DHP-200 product types can be configured with the help of a
Web User Interface (WebUI), which is described in chapter 8.
3 Radar Basics
3.1 Radar Distance Measurement Principle
The LPR®-1DHP-200 radar distance sensors use electromagnetic waves to measure the
distance and speed between two radars (secondary radar mode) or a single radar and a
reflector (primary radar mode).
The underlying measuring principle is based on the Round-Trip Time-Of-Flight (RTOF)
measurement between a transmitted radar signal and a received signal. The radar estimates
the time τ the radar signal needs to travel the unknown distance d from one radar to the other
(or to a reflector) and back. The distance is then calculated with the formula
where c is the speed of light.

3.2 Radar Beam and Opening Angle
The LPR®-1DHP-200 emits a high frequency electromagnetic radio signal with its integrated
antenna. The EM-wave is focused by a dielectric lens and creates a radar beam with an
opening angle (half power beam width, HPBW) of +/-2,5°.
Distance d in m
Radar beam 3dB
diameter in m

Table 3.1: Radar beam 3dB diameter vs. distance
Figure 3.1: Radar beam and opening angle.
3.3 Fresnel Zone
The area for radio transmission between two antennas is called Fresnel zone. The main part
of energy is concentrated in the first Fresnel zone.
The Fresnel zone has to be free of any obstacles to ensure that the
signal is not attenuated or interrupted.
The maximum radius of the first Fresnel zone (in the middle between two antennas) can be
calculated as follows:
= 0.5 ∙√ ∙
is the wave length and the distance between the two radar devices or a radar device and
a reflective target For a frequency of 61 GHz a wave length of approx. 0.005 m is
calculated. The maximum radius of the first Fresnel Zone is indicated by . The maximum
radius for different distances is given in Table 3.2.

3.4 Radar Modes
3.4.1 Primary Radar Mode
In primary radar mode, a single radar measures the distance and speed to a reflective object
/ target, typically a metal corner reflector. The following features differentiate the primary
radar mode from the other radar modes:
Suitable for ranges up to 50 m
Range depends on target radar cross section (RCS)
Very high update rate (up to 350 Hz)
Cost effective installation with a single radar
Distance measurements to passive objects enable additional applications for primary radar
mode,:
Presence / absence check (e.g. in a radar barrier)
Profile / measurement (e.g. of bulk material)
Detection of arbitrary objects (e.g. of personell or vehicles)
Figure 3.3 shows the typical setup of a LPR®-1DHP-220-R radar and a corner reflector for a
primary radar distance measurement.

Figure 3.3: Primary radar mode measurement setup
3.4.2 Secondary Radar Mode
In secondary radar mode two radars measure the distance and speed between each other.
The following features differentiate the secondary radar mode from the other radar modes:
Suitable for ranges up to 300 m
Distance is always measured to the partner unit and not to passive objects
Figure 3.4 shows the typical setup of two LPR®-1DHP-260 radars for a secondary radar
range measurement.

Product Family LPR®-1DHP-200 – Product Documentation
Figure 3.4: Secondary radar mode measurement setup
3.4.3 Diversity Radar Mode
In diversity radar mode four radar units are grouped into two pairs, which are mounted in a
way that two secondary range measurements are performed side by side separated by a
defined distance. The following features differentiate the diversity radar mode from the other
radar modes:
Suitable for ranges up to 500 m
Distance is always measured to the partner unit and not to passive objects
No clearance to reflective surfaces / objects required (see chapter 5.1; Fresnel zone still
needs to be free of obstacles)
If one of the two measurement paths fails, the system falls back to operation in
secondary radar mode and is therefore still available (error is indicated in diversity status
byte)
Figure 3.5 shows the typical setup of four LPR®-1DHP-281 radars for a diversity radar range
measurement.

Figure 3.5: Diversity radar mode measurement setup
3.5 Bandwidth Modes
The LPR®-1DHP-200 is able to operate in the 57 - 64 GHz band. Depending on your used
region and regulatory authority setting, a limited number of bandwidth modes are available
for selection in the WebUI.
The selected bandwidth modes have impact on the accuracy, resolution and range of the
radar. The dependency of performance and bandwidth mode with respect to regional
restrictions is depicted in chapter 10. It is recommended to use the 0.5 GHz or 2 GHz
bandwidth mode for standard applications.
Within a single bandwidth mode, multiple sync channels are available. For each channel
block, the effective bandwidth of a sync channel reduces with increasing sync channel
number.
3.6 Accuracy
To maximize the accuracy of a LPR®-1DHP-200 measurement setup, different error sources
which influence the accuracy need to be taken into account:
Mounting position
o
Adhere to the mounting instructions (see chapter 5) to minimize systematic errors
(e.g. horizontal or vertical offset and alignment).
Reflective surfaces and objects
o
Reflections of the radar signal, e.g. from walls, can cause distance errors in primary
and secondary radar mode which vary with the measured distance. Ensure the
recommended clearance to surfaces and objects described in chapter 5.1 or use
diversity radar mode to minimize errors caused by reflections.
Measurement noise
o
Measurement noise caused by the radar itself is the lower limit to the overall
accuracy. The noise will decrease with increasing bandwidth. For primary radar
mode, noise will increase with range and decrease with target radar cross section

Page 13 of 71
SYMEO Local Positioning Radar System
Product Family LPR®-1DHP-200 – Product Documentation
(dependent on target size, shape and material). In secondary radar mode noise is
constant within the specified range and will increase for ranges above.
Temperature drift
o
Changes in device and air temperature can lead to measurement offsets of approx.
+/-10mm. These errors vary slowly with time and can be countered by ensuring
constant environmental conditions, running a warm up phase of 30 minutes before
operation or by using a calibration reference.
3.7 Range
To maximize the range of a LPR®-1DHP-200 measurement setup the following aspects have
to be taken into account:
Mounting position
o
Adhere to the mounting instructions (see chapter 5). Ensure minimum alignment error
and vertical / horizontal offset and equal orientation (for secondary and diversity radar
mode)
Fresnel zone
o
Ensure the Fresnel zone is free of absorbing or reflecting objects
Reflective surfaces and objects
o
Reflections of the radar signal, e.g. from walls, can lead to a reduction of the received
signal strength and hence maximum range. Ensure the recommended clearance to
surfaces and objects described in chapter 5.1 or use diversity radar mode to counter
the effects caused by reflections
Target RCS (only primary radar mode)
o
In primary radar mode the maximum range depends on the target RCS (radar cross
section) which is a function of target size, material and shape. If the maximum range
is required use targets with a high RCS (e.g. the corner reflector MTE000958)
VGA value
o
For maximum range set the “VGA value” to the highest possible value that is allowed
in you regulatory domain. The WebUI will use your region settings to limit the “VGA
value” and hence range is reduced in certain regions (see chapter 10).
The minimum range of the sensors can be reduced to values below the specified minimum
distance by adapting the “VGA value”, the “RX attenuator” and the threshold settings (for
primary radar). This however affects the maximum range and the accuracy of the radar and
shall therefore only be applied by trained personell.

5 Mounting
5.1 General Mounting Instructions
Site-specific mounting instructions must be followed if available.
The more accurately the radar units and reflectors are aligned to each other, the better
the performance of the measurement setup will be in terms of accuracy and range.
The radar units and/or corner reflectors must move parallel to the radar beam in the
installation.
Ensure that the Fresnel Zone is free of obstacles.
Ensure that your measured distances lie in the specified measuring range (see chapter
10)
For primary and secondary radar mode (not for diversity radar mode) ensure that
reflective surfaces (e.g. walls, the roof, the floor, crane tracks) and other reflective objects
(e.g. poles, tubes, bridges, vehicles) have the recommended clearance to the center of
the radar beam that is in accordance with
Figure 3.3 and Figure 3.4).

SYMEO Local Positioning Radar System
Product Family LPR®-1DHP-200 – Product Documentation
For a primary radar distance measurement, typically a single radar unit and a recommended
corner reflector are mounted facing each other.
For operation in the primary radar mode the following issues must be considered:
The radar and the corner reflector must be installed in a way that the center of the corner
reflector is aligned with the center of the radar beam.
The reflector has to be either the nearest (first) target or the strongest target to be
detected properly.
Radar and radar reflector must be aligned to each other with maximum accuracy (at least
+/- 2,5°).
Minimum horizontal and vertical offset between radar and reflector must be ensured.
Follow the subsequent steps for proper installation of radar unit and reflector:
Mount a standard mounting bracket on one side of your measurement setup.
Mount the radar into the mounting bracket.
Mount a corner reflector to the other side of your measurement setup.
Mount the corner reflector in a way, that the opening faces the radar. The 3 corners of the
corner reflector opening must have equal distance to the radar.
Carefully align the radar to the corner cube reflector. To do so, it is recommended to use
a laser level fitted into the alignment aid, which should point at the reflector.
Fix the system by tightening the screws of the mounting bracket and the pipe clamp with
the correct tightening torques.
Connect the power supply and Ethernet cable with M12 connectors as specified in
chapter 4.3.1 and 4.3.2.
5.3 Mounting for Secondary Radar Mode
The Secondary Radar Mode is available for Product Types LPR®1DHP-260 and LPR®-1DHP-290.
For a secondary radar distance measurement, two radar units, one configured as a “master”
and one as a “slave” are mounted facing each other in a way, that the center of the emitted
radar beam of each unit hits the other unit. The master unit initiates the measurement while
the slave unit replies.
For operation in the secondary radar mode the following issues must be considered:
The two radar units must be installed in a way, that the center of the emitted radar beam
of each unit hits the other unit.
The two radar units must be oriented exactly equally or turned by 180° along the radar
beam axis (e.g. connectors of both devices facing downwards).
Minimum horizontal and vertical offset between both radar units must be ensured.
Both radar units must be aligned to each other with maximum accuracy (at least +/- 2,5°).

Follow the subsequent steps for proper installation of the radar units:
Mount a standard mounting bracket to one side of the measurement setup.
Mount the radar unit into the mounting bracket.
Repeat the first two steps on the other side of the measurement setup.
Carefully align both radar units to each other. To do so, it is recommended to use a laser
level fitted into the alignment aids. The laser dot should point to the other sensor for both
directions (Master -> Slave, Slave -> Master).
Fix the systems by tightening the screws of the mounting brackets and the pipe clamps
with the correct tightening torques.
Connect the power supply and Ethernet cable with the M12 connectors as specified in
chapter 4.3.1 and 4.3.2 to both stations. The Ethernet connection at the Slave unit is only
required for configuration and can be removed during operation. If removed install the
protective cap of the connector.
6 Quick Setup
This chapter gives a short introduction for the setup of the radar sensors with the help of the
WebUI. For detailed information on all possible settings, please refer to chapter 8.
6.1 Initial Setup
The following steps must be followed for the initial setup of all radar units:
Mount and align the radar units as outlined in chapter 5.
Connect the radar units to a power source (11 – 36V) and wait until booting is finished
(blue LED switches to red or green).
Connect the radar unit to a PC via Ethernet and open the Webinterface (WebUI) in a
Webbrowser (http://192.168.1.99). See chapter 7 for a detailed description.
Sign in to the WebUI (see chapter 8.2).
Choose country and regulatory authority.
6.2 Quick Setup for Primary Radar Mode
The following settings must be set in the WebUI for operation in primary radar mode:
Device -> Settings -> Measurement basics
o
Station mode = Primary
o
Bandwidth mode = Choose a bandwidth that fits your required range and accuracy
o
Channel block = Use recommended selection
o
Sync channel = different than any other LPR®-1DHP-200 sensor in range; for
neighboring measurement paths use only every fourth sync channel.

Page 27 of 71
SYMEO Local Positioning Radar System
Product Family LPR®-1DHP-200 – Product Documentation
Device -> Settings -> Measurement details
o
Target search mode = “First” if the reflector is the first target in range, “Strongest” if
the reflector is the strongest target in range.
The setting “Target search mode” highly impacts the behavior of the radar,
especially in multi target environments (see Figure 8.16). “First target” may
lead to distance measurements to unintended targets in the vicinity of the
radar (e.g. a person passing the radar beam). “Strongest target” may lead
to distance measurements to unintended targets present in the
background of your intended target (e.g. a wall behind a corner reflector).
Perform therefore always a test as described in chapter 6.4 to verify this
setting.
Review and Calibrate your measurement as stated in chapter 6.4.
6.3 Quick Setup for Secondary Radar Mode
The following settings must be set in the WebUI of the master and slave sensor for operation
in secondary radar mode.
Only the Master unit outputs range data.
Master
Device -> Settings -> Measurement basics
o
Station mode = Master
o
Bandwidth mode = Choose a bandwidth that fits your required range and accuracy
o
Channel block = Use recommended selection
o
Sync channel = different than any other LPR®-1DHP-200 sensor in range (except the
related Slave); for neighboring measurement paths use only every fourth sync
channel.
Slave
Device -> Settings -> Measurement basics
o
Station mode = Slave
o
Bandwidth mode = same as Master
o
Channel block = same as Master
o
Sync channel = same as Master
Review and Calibrate your measurement as stated in chapter 6.4.

o
Run a warm up phase of 30 minutes before calibration.
o
Compare the “current distance” to the actual distance in your measurement setup for
all ranges.
o
The mean value of the difference between the actual distance and the measured
distance is the reference-offset value, which needs to be added to the current
distance to match the radar’s and installation’s coordinate systems. The radar
therefore offers the setting “Measurements Details -> Customer specific offset”.
o
Make sure that the maximum and standard deviation of the difference between the
offset corrected measured and actual distance meets your accuracy requirements for
all possible distances in your measurement setup.
The LPR®-1DHP-200 are delivered with the fixed TCP/IP IP-Address
192.168.1.99.
7 Establishing a TCP/IP Connection
For configuration of the radar units, a TCP/IP connection has to be set up. Make sure that:
The unit is running.
The radar unit is connected with an appropriate Ethernet cable to a PC or a similar
device, which has a web browser installed.
The radar and the PC are located in the same subnet of the TCP/IP network. That means
that the first three numbers of the radar’s and PC’s IP-addresses must be equal.
No firewall is blocking the communication between PC and radar.
If PC and radar are not located in the same subnet open the TCP/IP network settings of your
network adapter in your operating system. Enter a fixed IP-Address e.g. 192.168.1.1 and the
subnet mask 255.255.255.0.

Station mode
o
Depending on the configuration the unit can either be run in secondary radar mode
(master measures the distance to slave) or in primary radar mode (radar measures
the distance to a reflective target)
Bandwidth mode
o
The LPR®-1DHP-200 supports different bandwidth modes, which impact the sensors
performance. For best accuracy, choose a large bandwidth. For maximum range and
update rate, choose a small bandwidth.
Channel block
o
The RF frequency range is grouped into several blocks. Each channel block defines a
set of available sync channels. It is recommended to keep the default value for
optimum performance
Sync channel
o
The sync channel determines the actual center frequency and bandwidth of the radar
signals and differentiates the LPR®-1DHP-200 links. The sync channel has to be the
same for a pair of master and slave but different than that of any other LPR®-1DHP200 device in range. The sync channel with the lowest number provides the highest
bandwidth in each channel block.
Changing bandwidth mode, channel block or sync channel influences the
sensors performance and reference plane. A recalibration and test of the
installation (see chapter 6.4), is therefore necessary after changing these
settings.

The VGA value determines the power of the transmitted signal.
SYMEO Local Positioning Radar System
Product Family LPR®-1DHP-200 – Product Documentation
The LPR®-1DHP-200 in primary radar mode can either output the distance to the first or the
strongest valid target. A target is valid, if its signal level is higher than a set signal level
threshold level profile, which is segmented into 3 range zones (short range, mid range, long
range). The start and end positions of the 3 range zones and their corresponding signal
threshold levels can be configured individually with the settings described above. An
example of the radar target spectrum (target signal strength vs. distance) recorded in a multi
target environment is shown in where the window for valid targets defined by the range
zones and their threshold levels is marked green. Targets outside of this window will be
ignored.
A change of the range zones and their threshold level settings is only necessary in a multi
target environment and should only be conducted by trained personal.

SYMEO Local Positioning Radar System

Figure 8.28: Diagnostics - RSSI over distance diagram
This diagram shows the recorded distance-signal strength pairs since the last power-on. You
can use it to detect abnormal signal propagation routes at certain constellations of the two
LPR® stations, as the signal strength should decrease with increasing distance.
The diagram is automatically refreshed every 10 seconds.
The distance axis displays the distance between the two LPR® stations, and the RSSI axis
the received signal strength in dB. As the signal strength at specific distances may vary, the
statistical distribution of the signal strength is also recorded. Displayed are the mean
received signal strength, the 10 % quantile and the 90 % quantile. The quantiles give you
information about how many recorded signal strength values were lower than the
corresponding line. 10 % of the recorded signal strengths were lower than the 10 % quantile
line and 90 % were lower than the 90 % quantile line, leaving 80 % in between those two
lines. This way you get an idea of the signal strength distribution per distance without
including extreme outliers. This helps identifying distances with increased signal distortions
(e.g. due to multipath signal propagation), as the variance of the signal strength there usually
increases.

The diagram is automatically refreshed every 10 seconds.
The distance axis displays the distance between the two LPR® stations, and the

9 The Customer Protocol
The customer protocol (Binary Protocol XP) is the standard data protocol between LPR®1DHP-200 units and users for exchanging measurement and relay data with the help of
different data types in binary data format. The transfer of a data packet of a certain data type
is done in single data frames. The data can be transferred either via TCP/IP or UDP protocol.
All settings related to the customer protocol can be found in the WebUI
under Device -> Settings -> Customer protocol
The default TCP/IP and UDP port of the customer protocol interface is
3046.
The customer protocol is not output on slave units.
9.1 General Description
9.1.1 Structure of a Data Type
Each data type has a fixed structure and length.
data type.
Each data packet begins with the START symbol (0x7e). TYPE indicates the type of the data
packet. The DATA field contains the relevant data. The CRC-field contains the check sum.
The data type ends with the END symbol (0x7f).
All multi byte integers (e.g. CRC field) are encoded in Network-Byte-Order (Big-Endian). All
signed integers are represented in two's complement.
A custom protocol length which is bigger than the standard protocol
length can be set. The data packet is then zero-padded (after the END
symbol) to the selected protocol frame length before the data packet is
sent.
Figure 9.1: Structure of a data type
Figure 9.1
shows the general structure of a
9.1.2 CRC
The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the CRC. The CRC is calculated
over the TYPE and DATA field.

9.2 Data Types
9.2.1 Type 0x16 – Distance Data
Direction: LPR®-1DHP-200 Unit → User
The data type 0x16 is the standard output data type. It contains measurement data, system
status information and settings. The default protocol frame length is 47 bytes.
Table 9.1 shows the structure of a 0x16 data packet.
The standard customer protocol length of the LPR®-1DHP(-R) sensor
(predecessor) was 50 bytes which has to be taken into account if a
LPR®-1DHP-200 is used to replace it.
The data packets are output with the internal update rate or the chosen update rate.
The internal measurement rate depends on the used radar mode, FFT
size and averaging setting. The output rate of the interface equals the
internal measurement rate if no custom output interval is set.
