2.1 Radar system overview
The radar system is intended for use in a marine environment. It consists of a rotating scanner
protected by a dome connected to a radar processor module by a prefabricated 15m (49ft)
interconnection cable. A longer 20 m (65.5 ft) interconnection cable may be ordered
separately. Scanner cables must be installed by a qualified radar technician.
A network or serial cable is to be used to connect the radar processor to a display head.
An interconnection cable should only be installed by a qualified radar technician.
The radar processor module connects to the various display heads using three different
protocols. These are:
Ethernet. For more information on connecting via
Ethernet (see "Connect Simrad GB40 or
Northstar 8000i" page 30).

2.2 Warnings
Use the radar at your own risk. Your radar was designed for use as a navigation aid. It
should not be used for purposes that require precise measurements of direction,
distance, topography or location. Always compare the navigation information received
from your radar with data from other navigation aids and sources. When a conflict
arises between the navigation data from your radar and data from other navigation
aids, make sure you resolve the conflict before proceeding with navigation. A
CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN NAVIGATION
INFORMATION.
8 | Introduction to the Navico radar system
Caution: International Regulations for Preventing Collisions at Sea mandate indicate
that when radar is on a vessel, the radar must be used at all times, regardless of
weather conditions or visibility. Numerous court decisions have not only ruled the
radar must be used, but that the radar operator must be knowledgeable in all
operational aspects of radar performance; or otherwise face a greater risk of liability
if an accident occurs.
WARNING: High Voltage Hazard
There is dangerously high voltage present within the radar scanner unit. Technicians
must exercise extreme care when working inside the unit. ALWAYS remove power
before removing the cover. Some capacitors may take several minutes to discharge,
even after switching off the radar. Before touching the magnetron or any high voltage
components, ground them with a clip lead.
WARNING: Microwave Radiation Hazard
The microwave energy radiated by a radar antenna is harmful to humans, especially
to the eyes. NEVER look directly into an open waveguide or into the path of radiation
from an enclosed antenna. Radar and other radio frequency radiation can upset
cardiac pacemakers.
If someone with a cardiac pacemaker suspects abnormal operation, immediately turn
off the radar equipment and move the person away from the antenna. Turn off the
radar whenever it is necessary to work on the antenna unit or other equipment in the
beam of the radar.
Note: Most countries accept that RF power density levels below 100 W/m² cause no significant
RF hazard.

Install the radar | 9
A radar unit should only be installed by a qualified marine technician, as potentially
lethal high voltage is present along with heavy rotating parts.
There is a transmit interlock that prevents radar transmissions if the scanner is not
rotating. However, a high voltage remains for a period of time after the system is
turned off. If you are not familiar with this type of electronics, consult with a trained
service or installation technician before attempting to service any part of the
equipment.
Installation includes:
• mechanical mounting
• electrical wiring
• configuring the display or network system to work with the radar
• adjusting the radar for proper performance
Don't take any shortcuts, and follow these instructions carefully!
This section explains how to:
• choose the correct location for the scanner
• install the scanner on a power boat or a yacht
• choose the correct location for the radar processor
• install the radar processor
Read the important warning and safety information in the Preface before you install
the radar.
Note: For best MARPA functionality, heading information received by the radar processor needs
to be a minimum of 10 Hz, depending on the display head being used. See the section relating
to the display head you are connecting to for more information.

10 | Install the radar
3.1 Check the radar parts
The Navico radar system consists of a scanner, a radar processor, and associated cables. some
of which need to be ordered separately.
There are three main components of the radar system:
• The radar scanner
• The radar processor. The radar processor must match the power output of the scanner. For
example, a 2 kW Scanner connects to a 2 kW processor box. Connection cables to attach to a
display head are not shipped with this item and they must be ordered separately. The cables
required will depend on the type of display head being used with the radar system. Later in
this manual, you will find information about connecting particular display heads.
• Radar connection kit. This varies depending on display head that you are connecting to. Later
in this manual, you will find information about connecting particular display heads.
Unpack the boxes carefully and check the contents against the packing lists. If anything is
missing, contact your distributor.
Note: A parts list of what comes with scanner can be found inside the scanner packaging.

3.2 Choose the scanner location
The radar's ability to detect targets depends greatly on the position of its scanner. The ideal
location for the scanner is high above the vessel's keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected.
Also see the sections on installing the scanner on a power boat or yacht.
When you're deciding on the location, consider the following:
• the length of the interconnection cable supplied with your radar is usually sufficient. If you
think you'll need a longer cable, consult your dealer before installation, because a longer
cable may reduce the performance of the radar.
• if the roof of the wheelhouse is the highest existing location, consider installing a radar mast
or a pedestal on which you can mount the scanner. You may also need to construct a
working platform for your own safety during installation and servicing work.
• if you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain
away from it rapidly.
• if you locate the scanner on the mast, position it on the forward side so that there is a clear
view to the front of the vessel.
• the scanner is usually installed parallel to the line of the keel.
• ensure that the location site provides the scanner with a clear view of the front of the vessel.
DON'T DO THIS!
• DON'T install the scanner too high up, where its weight will alter the stability of the vessel
and cause degradation of the radar picture over
short ranges (see "How to find the optimum
height for the scanner" page 15).
• DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may cause
the equipment to break down. Soot and smoke will degrade the performance of the radar.
• DON'T install the scanner close to the antennas of other equipment such as direction finders,
VHF antennas, GPS equipment and so on, because it may cause interference.
• DON'T install the scanner where a large obstruction (such as an exhaust stack) is at the
same level as the beam, because the obstruction is likely to generate false echoes and/or
shadow zones.
• DON'T install the scanner where it will be subjected to strong vibrations (such as a derrick
post) because these vibrations will degrade the performance of the radar.
• DON'T install an open array close to halyards or flags because the wind could wrap these
around the scanner and jam it.
DON'T install the scanner inside of the recommended compass safe distances of any
navigation instruments such as the magnetic compass and the chronometer. The
compass safe distances are as follows:
2 kW radar STD 0.7m (2.3 ft) / STEER 0.5 m (1.6 ft )
4 kW radar STD 2.0 m (6.5 ft) / STEER 1.5 m (5 ft)
Install the radar | 13
3.3 Power boat installations
Normally, you should install the scanner horizontally, to produce an equal sweep around the
boat:
However, when a power boat is traveling at high speed, the bow rises up out of the water and if
the elevation angle (trim) of the bow is raised up so that it equals, or exceeds, 50% of the
vertical beam width of the radar, this can cause two problems:
• Ahead of the power boat, the beam is projected too high to sweep the water surface
effectively. Targets can be missed completely or appear at a very poor resolution on the
display screen.
• Astern of the power boat, the beam is projected too low and is concentrated over a small
area of water so that sea clutter becomes a problem on the display screen.
In this case, you're recommended to install the scanner so that it is tilted down at the front, at
an angle that will produce an almost horizontal sweep when the power boat is running at speed.
14 | Install the radar
3.4 Yacht installations
Normally you should install the scanner horizontally, to produce an equal sweep around the
yacht. However, a yacht heels over to the lee side, and when the heel angle exceeds 50% of
the vertical beam width of the radar, this can cause two problems:
• On the windward side of the yacht, the beam is projected too high to sweep the water
surface effectively. Targets can be missed completely or appear at very poor resolution on
the display unit.
• On the lee side of the yacht, the beam is projected too low and is concentrated over a small
area of water so that sea clutter becomes a problem on the display unit.
In this case, you're recommended to install the scanner on a gimbal mounting so that it can
operate effectively in a heavy swell or when the yacht is heeled over.
3.5 How to find the theoretical maximum detection range
Propagation of the radar beam can vary, depending on the properties of the air through which it
is traveling. Under normal conditions, the distance that the radar beam travels is approximately
10% further than the distance to the optical horizon.
You can calculate the theoretical distance traveled by the radar beam using the following
formula:
D = 2.23 (√h1 + √h2)
where:
• D is distance traveled by the radar beam
• h1 is the height above sea level of the scanner
• h2 is the height above sea level of a target
An example is shown below:
Install the radar | 15
In this example, the scanner is installed on the vessel at a height of 3 m (10 ft) above sea level
(h1). Island A is 10 m (33 ft) high (h2) and for comparison, island B is 5 m (16.4 ft) high (h2).
Both islands are at a distance (D) of 10 nautical miles from the vessel.
Calculations using the formula show that, at this distance, the radar can only detect objects that
are more than 7.6 m (25 ft) high, which means that island A is shown on the radar but island B
is not shown.
Remember that:
• The maximum detection range of the radar is limited by the curvature of the earth's surface
under normal conditions of wave propagation.
• Bad weather conditions can reduce the maximum detection range.
3.6 How to find the optimum height for the scanner
The optimum height for the scanner is as close as possible to the A-B line for best performance.
How to find the A-B Line:
The vertical extent of the radar beam is 2θ°, so most of the radar beam is concentrated within
this angle, meaning that outside of this angle, the radar beam will be very weak.
Scanner model θ° value (half the -3 dB beam width)
2 kW 15
4 kW 12.5
An example of an A-B Line is shown in the picture. If you install the scanner below the A-B line,
the scanner will be too low. It will be difficult to acquire distant targets and the superstructure
will be more likely to impede the passage of the beam and generate false echoes. If the scanner
is installed too high above the A-B line, the beam will miss close targets and increase sea clutter
return.
You can find the A-B line for any vessel as follows:
• Using a scaled drawing of the vessel, lay a rule along the line of the main deck and
continue this forwards as a dashed line extending beyond the bow.
• Using a protractor, measure the θ° value (for your scanner model) below the dashed line
at the bow and draw in a new line along this angle.
• Extend the new line back beyond the bow of the vessel. This is the A-B line.
16 | Install the radar
3.7 How to reduce false echoes and shadow zones
False echoes can be produced on the radar display if the scanner is installed too close to an
object on the vessel's superstructure. This object can block the radar beam and reflect it back,
generating false echoes and shadow zones.
If you are having problems with false echoes and/or shadow zones, re-install the scanner at a
higher location where the radar beam will be clear of any obstructions.
If this is not possible, try relocating the scanner away from the central keel line of the vessel to
the starboard side. This will move any shadows to the port side, maximize the radar view of
your give way sector, and ensure a clear view of the area around the vessel at the bow.
Use the following formula to calculate the distance that you'll need to move the scanner:
Ls = 0.4R + D/2 (when R is less than 49 ft [15 m])
Ls = 0.025R + D/2 (When R is greater than or equal to 49 ft [15 m])
where:
Ls = distance to be moved from the keel line
D = diameter of the obstacle
R = distance between the antenna and the obstacle
Install the radar | 17
3.8 Install the scanner unit
Important: Remember that you must screw the bolts into place from the under side of the
location site, because the shape of the dome prevents you from installing the bolts from the top
side. Ensure that you can access the under side of the location site before drilling.
Find the paper mounting template and tape it securely to the chosen location site. Before
drilling, check that:
• the location site is not more than 0.6" (15 mm) thick.
• You have oriented the mounting template correctly so that the front of the scanner unit will
face the front of the vessel; and
• the location site allows the drain hole to empty.
Drill the four holes plus the drain hole where shown. Remove the mounting template, then
position a rubber washer over each hole on the scanner. Ensure that the slot in the rubber
washer is aligned with the rib on the scanner.
Position the scanner carefully over the bolt holes so that they are aligned with the holes of the
rubber washers and the drill holes.
Place a spring washer then a plain washer onto each bolt, as shown. Screw each bolt into each
drill hole from the under side of the location site, and tighten securely
Note: Use the bolts supplied as these are hardened stainless steel and the correct length.
3.9 Install a scanner on a trestle
Depending on your chosen location for the scanner, it may be easier to install the scanner if you
fabricate a trestle (or radar mast) on which you can mount the scanner.
The trestle must be sturdy and secure, and capable of supporting the scanner in all weather
conditions.
You are recommended to install the base of the trestle parallel to the water surface.
Orient the trestle so that the cable inlet on the scanner will face the stern, and so that the
scanner can be mounted at the correct angle (as discussed in the "Power boat installation"
section).
Make sure that the edges of the trestle won't trap water.
3.10 Install the radar processor
Install the radar processor in a dry location away from spray, rain, drips and condensation.
The radar processor must be located where it can be easily connected to the ship's ground, the
interconnection cable, the power cable and the radar communications cable or the network
cable. Check that these cables and the ship's ground can easily reach the radar processor
BEFORE you drill.
The radar processor dimensions are shown on the installation template. Follow the instructions
on the installation template to install the radar processor.

If you have the standard 2 kW radar system, the scanner is supplied with the 15 m (49 ft)
interconnection cable already connected and you can ignore this section.
If you have ordered the longer 20 m (65.5 ft) interconnection cable, follow the guidelines in this
section.
Note: An interconnection cable should only be installed by a qualified radar technician.
• Unscrew and remove the cover of the scanner, lifting it vertically to avoid bumping it
against the antenna.
• Carefully lift the main unit and stand it upright in the slot on the scanner casing:

• Remove the shield cover from the underside of the main unit to expose the connector
locations and ground terminal location.
• The broken line shows the route for the interconnection cable.
• Identify the connector ends B, C, and D on the 2 kW interconnection cable. Connector D is
a grounding strap.
• Place the locking nut, gasket A and gasket B over the end of the interconnection cable in
the order shown, then push the interconnection cable through the cable entry point into
the radome. (Ensure that you push through sufficient cable to easily join the connectors.)
• At the cable entry point, take care that the grooves in gaskets A and B are opposite each
other (see the figure). Tighten the locking nuts to hold the interconnection cable firmly in
place and to provide a waterproof seal.
