摘　　要：通过计算机仿真获得箔条云回波数据对箔条云干扰和抗箔条云干扰研究具有重要意义,现有的各种仿真方法存在着许多缺陷,诸如计算量大或者不能体现不同体制雷达回波的特性等.对箔条云性质进行了简要的分析,以舰载箔条弹为背景,对箔条云的分布状况等特征进行了适当的简化假设,并在此基础上建立了一种箔条云回波数学模型.该模型的基本思想是将箔条云等效为滤波器,滤波器输出信号即为箔条云雷达回波.计算机仿真实验表明提出的模型是实用的.It＇s important for the research of chaff jamming or anti-jamming to get the radar echo of chaff via computer simulation, but there are several disadvantages with the existed methods, such as large computation cost or no presenting different echoes from different system radar and so on. A brief analysis of chaff cloud characteristic is presented. After making a predigestion to the chaff cloud on the background of chaff dispenser of naval ships, a echo model is put forward. The chaff cloud is regarded as a filter, and the filter＇s output is the radar echo from the chaff cloud, which is the basic idea of this model.Computer simulation shows that the model is practical.
