With rapid development of computer modeling and simulation technology and digital electronic technology,radar simulation technology becomes an auxiliary means absolute necessary for radar system design and performance verification. Target echo simulation can be used to verify radar performance by simulating target echo signals with feature information like distance,direction,Doppler speed,amplitude and so on. A kind of store and forward hardware-in-the-loop radar target echo simulation system is presented. Operational principle of target echo signal simulation is described,and process of using characteristic data to calculate target feature information in radar target echo simulation is depicted.
