摘　　要：论述了一种中频雷达杂波信号的模拟方法及其硬件实现,该模拟器采用软硬件相结合的方法,由计算机实时解算每个杂波单元的幅度、距离、散射系数等参数,然后将数据发送到硬件电路中,由硬件电路完成对雷达信号的采样、调制、幅度控制、恢复,最终产生杂波信号并输出。In this paper, a simulation method and hardware realization of intermediate frequency （IF） radar clutter signal is discussed. The method combining software with hardware is used in the simulator. Parameters such as amplitude, distance and scattering coefficient of each radar clutter unit are calculated in real time through computer, then the data are sent to the hardware circuit, which is used to complete the sampling, modulation, amplitude control and comeback of radar signal, and finally generate and emit the clutter signal.
