RADAR BLOCK DIAGRAM AND OPERATION
The transmitter may be an oscillator,such as a magnet, that is pulsed by the modulator to generate a repetitive train of pulse. The magnet has probably been the most widely used of the various microwave generators for radar.A typical radar for the detection of aircraft ranges of 100 or 200 might employ a peak power of the order of a megawatt, an averages power of several kilowatts, a pulse width of several microseconds, and a pulse repetition frequency several hundred pulses per second. The waveform generated by the transmitter travel via a transmission line to the antenna.where it is the function of the radiated into space.A single antenna is generally used for both transmitting and receiving.The receiver must be protected from damage caused by the high power of the transmitter.This is the function of the duplexer also serves to channel the returned echo signals to the receiver and not to the transmitter. the duplexer might consist of two gas-discharge devises,. one know as a TR (transmit-receive)and the other ab A T R (anti-receive) the TR protects the receiver during transmission and the A T R directs the echo signal to the receiver during reception
