Page 13 - 5 kW radar system overview
10 25 kW radar system overview The radar system is intended for use in a marine environment. The 25 kW radar system consists of a scanner and an open array, connected to the 25 kW radar processor by a prefabricated interconnection cable which is available in two lengths (NS003105 or NS003106). where...
Page 14 - Install the radar; Choose the scanner location
11 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 ...
Page 16 - Power boat installations
11.1.1 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 equa...
Page 17 - Yacht installations; How to find the optimum height for the scanner
11.1.2 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 o...
Page 18 - How to find the maximum detection range
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 ins...
Page 19 - How to reduce false echoes and shadow zones; Install an open array scanner on a trestle
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...

Ideally, the compass should draw less than 100 mA. (If this is not possible, power the compass using a separate 12 V source.) 12.12 Connect the power cable The power cable to the radar processor is NOT supplied for either the 6000i or 6100i system or the 8000i system. Power must be supplied through ...
