rotates to scan the entire
surrounding area. Bearings to the target are determined by the orientation of the antenna at the moment when the reflected echo returns.
radar antenna (called the scanner)
Considerable power is required by a radar for transmit mode, of up to 400 watts even in the smaller sets. The supply is usually a small solid state power pack or motor alternator or a generator with larger sets.
Power Supply
Radars transmit directional microwave radio pulses with a rotating ariel (the scanner) in a 360o circle around the machine. It detects the bearing and range of echoing pulse returns from significant surrounding targets to produce a map like display.
