摘　　要：论述了雷达视频模拟器的设计思想及用计算机模拟目标及杂波的方法。模拟器采用PC机加数字信号处理器 (digitalsignalprocessor,DSP)组合的结构 ,根据多功能视频信号模拟的要求 ,利用伪独立杂波产生法 ,实时产生包含目标和杂波的视频回波信号。该模拟器经与雷达信号处理机联调 ,证明此设计合理 。Methods for designing a radar video signal simulator and simulating radar targets and clutter are discussed in this paper. The structure composed of general computer and DSP is adopted in the design of the simulator on the basis of the requirements of multifunction video signal simulator, and the real time video signal containing target and clutter is generated by the method of random extraction. The design has been verified by the combination of the simulator and the radar signal processor.\;
