摘　　要：介绍了通过软件和硬件相结合的办法,实现多体制多频段搜索雷达信号和处理的模拟。该模拟器通过设置和加载不同体制的雷达参数和软件,采用灵活的数字波形产生方式形成数字基带信号,经混频放大形成射频小信号,再通过方向图模拟形成不同形式的雷达回波信号,从而实现通用搜索雷达的模拟。仿真证明该模拟器是可行的。A simulator used for simulating the echo and signal processing of different system, frequency band and function radars is presented in this paper. The simulator is designed by software-hardware mixed means. The general-purpose surveillance radar simulator is realized as follows：firstly setting and loading the different parameters（including radar, target, clutter etc. ） on software, then generating the digital baseband signal by a flexible digital waveform generating method, and forming the small RF signal through mixing and amplifying the baseband signal, and finally obtaining different simulated radar echo by means of antenna pattern simulation of the RF signal. The simulation results show that the radar simulator is effective.
