RADAR (Radio Detection and Ranging) is a system used to detect distant objects by transmitting radio waves and detecting the radio waves that bounce back. The key components of a RADAR system include a transmitter, receiver, antenna, display, and power supply. RADAR uses the Doppler effect to measure how fast targets are moving by detecting changes in the frequency of reflected radio waves. Applications of RADAR include weather forecasting, air traffic control, search and rescue operations, and mapping.

8. Radar equation : The power P r returning to the receiving antenna is given by the radar equation: where; P t = transmitter power G t = gain of the transmitting antenna A r = effective aperture (area) of the receiving antenna σ = radar cross section, or scattering coefficient, of the target F = pattern propagation factor R t = distance from the transmitter to the target R r = distance from the target to the receiver.
