PLEASE READ CAREFULLY BEFORE USE
WARNING indicates a potentially hazardous situation which, if not avoided, could
result in death, serious injury or damage to property
2.1 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. Caution:
International Regulations for Preventing Collisions at Sea mandate 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
Dangerously high voltages are 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.

3.1 2 kw Radar overview
The 2 kW radar system is intended for use in a marine environment. It consists of a Scanner
protected by a 450mm diameter dome connected to the 2 kW radar processor module by a
prefabricated 15m (49ft) interconnection cable (AA010088), The cable is attached to the dome at
the factory. A longer 20m (65.5 ft) cable is also available which has to be or dered se paratel y and
will need to be exchanged by a qualified radar technician.
Note Changing the scanner cable should only be done by a qualified radar technician.
The radar processor module connects to the various display heads using three different protocols.
These are:-

4 Install the radar
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: Form MARPA functionality be more accurate you must send heading data at greater than
10Hz into the radar processor module. This is different for different display products. Please see
the section relating to the display you are connecting to for more information
4.1 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 aren't any obstacles.
The higher the installation position, the longer the radar ranging distance, but the minimum range
that the radar can detect targets increases the higher that the radar is mounted.
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 Northstar 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, consi der 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 spr ay can drai n a way
from it rapidly.
• if you locate the scanner on the mast, position it on the forward side so tha t there is a clear
view to the front of the vessel.
• the scanner is usually installed parallel to 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").
• DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may cause
the equipment to breakdown and 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 2.3 ft (0.7 m) / STEER 1.6 ft (0.5 m)
4 kW radar STD 6.5 ft (2.0 m) / STEER 5 ft (1.5 m)
6 kW radar STD 7.5 ft (2.3 m) / STEER 5.7 ft (1.75 m)
10 kW radar STD 7.9 ft (2.4 m) / STEER 6 ft (1.8 m)
25 kW radar STD 7.9 ft (2.4 m) / STEER 6 ft (1.8 m)
4.2 Power boat installations
Normally, you should install the scanner horizontally, to produce an equal sweep around the
power boat:
However, when the 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 is tilted down at the front, at an
angle that will produce an almost horizontal sweep when the power boat is running at speed.
4.3 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 resoluti on 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.
4.4 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 wi thin
this angle, meaning that outside of this angle the radar beam will be very weak.
Scanner model
2 kW 15
4 kW 12.5
6 kW 10
10 kW 10
25 kW 10
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 fal se echoes. If the scanner is
installed too high above the A-B line, the beam will miss close targets and increase sea clutter
return.
θ° value (half the -3 dB beam
width)
You can find the A-B line for any vessel as follows:
• Using a 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.
4.5 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's
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:
In this example, the scanner is installed on the vessel at a height of 10 ft (3 m) above sea level
(h1). Island A is 33 ft (10 m) high (h2) and for comparison, Island B is 16. 4 ft (5 m) 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 25 ft (7.6 m) 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
4.6 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 the false echoes and shadow zones.
If you're having problems with false echoes and/or shadow zones, check if it's possible to reinstall the scanner at a higher location where the radar beam will be clear of any obstructions.
If not, 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
4.7 2 kW scanner dimensions
Before starting the installation, use the drilling template to identify the:
• cable inlet
• drill holes
• front and rear of the radome
• location of the drain hole (ensure that your chosen location allows the drain hole to empty).
The 2 kW scanner dimensions are shown:
4.8 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.
4.9 Install the 2 kW scanner unit
IMPORTANT: Remember that you must screw the bolts into place from the underside of the
location site, because the shape of the dome prevents you from installing the bolts from the
topside. Ensure that you can access the underside of the location site before drilling.
Find the paper installation 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 template correctly so that the front of the scanner unit will face the front
of the vessel.
• the location site allows the drain hole to empty.
Drill the four holes where shown to a maximum depth of 0.6" (15 mm) plus the drain hole.
Remove the 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 underside of the location site, and tighten securely with a 5.31" (135 mm)
torque wrench.
NOTE: Use the bolts supplied as these are hardened stainless steel and the correct length.
4.10 Install the radar processor
Install the radar processor in a dry location away from spray, rain, drips, and condensation.
The location site must allow you to easily connect the radar processor to the shi p'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 drilling template. Follow the instructions on the
drilling template to install the radar processor.
5 Check the 2 kW radar parts
