Development of digital RF memory based target echo simulator for Doppler RADARS

Radar target echo simulators are needed for calibrating and testing of various Radar systems. A low cost novel implementation of target echo simulator is demonstrated in this paper. Various parameters like target range, range rate, atmospheric attenuation had been simulated using Digital RF Memory technique. The simulated target echo is then sent into the radar signal for test and evaluation. The echo simulator is programmable and can be used for testing of various radar systems.
