摘　　要：介绍了一种雷达多目标模拟器的工作原理、组成和功能。该模拟器与雷达之间采用空间辐射的对接方式 ,接收雷达发射的信号 ,进行延时与频率的相参调制和幅度调制 ,产生多个模拟运动目标的射频信号 ,配以气球和飞机校飞 ,可以有效检验相控阵测量雷达的多目标跟踪性能和工作方式。The functions, composition and design principle of a multitarget simulation system are introduced. the multitarget simulation system receives signal from radar through radiation and performs time delay and frequenc staggered modulation and amplitude modulation. Multitarget RF signals are also generated by it. By using the multitarget Simulation system with balloon or plane, the multitarget tracking performance and operation modes of the phased-array radar can be checked. The multitarget simulation system is successfuly used in performance test of a phased-array radar. [
