10 25 kW radar system overview The radar system is intende d for use in a marine environment. The 25 kW radar system consists of a sca nner and an open array, connected to the 2 5 kW radar processor by a prefabricated inte rconnection cable which is availa ble in two lengths (NS003105 o r NS003106). where A is the radar processor, B is th e vessel&[...]

11 Install the radar A radar unit should only be installed by a qualifie d 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 fo r a period of time after the system is turned [...]

DON'T DO THIS!  DON'T install the scanner too high up, wher e it s 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 ex haust outlets. The heat emissions may cau[...]

11.1.1 Power boat installations Normally, you should install the scanner horizonta lly, to p roduce an equal sweep around the powe r 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 bea m width[...]

11.1.2 Yacht installations Normally you should install the sc anner horizontally, to produce an equal sweep around the yac ht. However, a yacht heels over to the lee side, and when the heel angle ex ceeds 50% of the vertical beam width of the radar, this can cause two pr oblems:  on the windward side of the yacht, the beam is projected too high [...]

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 th e passage of the beam and generate fals e echoes. If the scanner is installed too high above the A-B line, the beam wil[...]

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 curva ture of the Earth's surface under normal conditions o[...]
