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.

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.
