摘　　要：雷达仿真系统是为检测雷达设备的抗干扰能力以及在各种电磁环境下的工作性能而设计的,包括有源干扰和无源干扰的模拟仿真。本文阐述了无源干扰即杂波的散射模型和仿真过程;从同步脉冲干扰的基本原理出发,阐明在雷达工作环境仿真系统中距离拖引、速度拖引、虚假目标等同步脉冲有源干扰的设计和实施过程;并针对工作在搜索和跟踪交替模式下的相控阵雷达提出自适应综合干扰方式;最后分析并总结了系统仿真时为真实、有效地模拟电磁干扰环境应注意的关键问题。The radar simulation system for both active and passive jamming simulations is designed to detect the antijamming capability of radar equipment and the operating characteristics of various electromagnetic environments. This paper expands the scattering models and the simulation process of passive jammings, namely clutters. Based on the sync pulse jamming principles, it also describes how to design and implement sync pulse active jammings, such as the range pull-off, velocity pull-off and false targets. Aiming at the phased array radars working in alternate modes of scanning and tracking, the paper puts forward a self-adapting synthesis jamming mode. At last, it analyzes and sums up the key problems in authentically and effectively simulating electromagnetic jamming environments.
