摘　　要：为了方便有效地对PD雷达进行干扰抗干扰技术研究,需要利用某种计算机仿真技术,建立一套仿真系统,最大程度地模拟PD雷达干扰环境。基于此目的,文章首先描述了PD雷达发射信号的数学模型,重点研究了常见的两种PD雷达有源干扰方式及其作用机理,并采用MATLAB/SIMULINK仿真技术对信号,干扰等模块进行建模。仿真结果显示,建立的模型可以有效模拟对PD雷达实施的各种干扰。建模过程简单有效,因此,可以在该系统上进一步进行干扰手段改进或者抗干扰性能的仿真,有助于PD雷达干扰抗干扰技术的研究。In order to study radar countermeasure technology conveniently, it is needful to have a set of system with computer simulation method for simulating the jamming environment of PD radar. Based on it, the math model of PD radar signals is depicted, two common active jamming ways and their function mechanism are stressed, and the method with MATLAB/SIMULIN to form the signal model and jamming model is introduced. The simulation results show that the model can simulate these jamming to PD radar. The method is simple and effective, based on it, further simulation for the improved radar jamming or the performance of anti - jamming method can be done. It is helpful for the research of PD radar countermeasure field.
