A general radar surface target echo simulator

A general radar echo simulator system proposed in this paper is to satisfy the various needs of the radar signal processor testing. This simulator is based on the type of echo data playback device, the surface target echo data is pre-calculated and stored in the device at first, then according to the external timing PRI signal, echo data is read out to the device processor, on which target information is modulated and interpolation operation is made. After the DA Converter, the radar echo is created. The system is simple and easy to implement general.
