Given below are 6 major parts of a RADAR SYSTEM:

• A TRANSMITTER: It can be a POWER amplifier like a Klystron, Travelling Wave Tube or a power Oscillator like a Magnetron. The signal is first generated using a waveform generator and then amplified in the power amplifier.
• Waveguides The waveguides are TRANSMISSION lines for transmission of the RADAR signals.
• Antenna: The antenna used can be a parabolic reflector, planar arrays or electronically steered phased arrays.
• Duplexer: A duplexer allows the antenna to be used as a transmitter or a receiver. It can be a gaseous device that would produce a short circuit at the input to the receiver when transmitter is working.
• Receiver: It can be superheterodyne receiver or any other receiver which consists of a processor to process the signal and detect it.
• Threshold Decision: The output of the receiver is compared with a threshold to detect the presence of any object. If the output is below any threshold, the presence of noise is assumed.
