摘　　要：he raw echo simulator, one of the fundamental components of Chinas Cband spaceborne Synthetic Aperture Rador(SAR) ground demonstration system is presented in this paper. The function of the raw echo simulator is to provide realistic radar return in real time, and form a closed loop system together with the onboard radar equipment and the signal processor. It can be used to verify the performance of the SAR system and imaging algorithm before practical launching. The computer simulation models for the raw echo simulator are analyzed, and some preliminary results of the simulated experiments are given.ＡＲａｗＥｃｈｏＳｉｍｕｌａｔｏｒｆｏｒｔｈｅＣ┐ＳＡＲＧｒｏｕｎｄＤｅｍｏｎｓｔｒａｔｉｏｎＳｙｓｔｅｍＣａｏＰｅｎｇｚｈｉ（曹鹏志），ＸｕＲｏｎｇｑｉｎｇ，ＬｉｕＹｏｎｇｔａｎ（ＲｅｓｅａｒｃｈＩｎｓｔｉｔｕｔｅｏｆＥｌｅｃｔｒｏｎｉｃＥｎｇｉ...
