Abstract
Modern radar systems include radar signal processors, data collectors, and radar data processors, besides traditional antennas, transmitters, receivers, and monitors. Signal processors are used mainly for target signal detection and for restraining the irrelevant signals of noise wave disturbances from earth or ocean, multi-path effects, atmospheric environment, universal noises, and man-made disturbances. The video output signals after signal processing are compared with certain detection threshold. If the signals are beyond the detection threshold, we “discover” targets.
