Three-Channel Real-Time Clutter Simulator for Doppler Radar

A three channel real time clutter simulator for Doppler radar is developed by applying a new real time signal reconstruction and modulation technic.Windowing and overlapping the series time domain sequence instead of simple combination,the ratio of signal to noise increases from 30 dB to 60 dB.At the same time,we refrain mirror frequency effectively with the method of digital quadrature modulation (DQM).
