摘　　要：箔条干扰是一种重要的无源干扰手段。在一定的海况和环境条件下,箔条假目标布放策略和舰船规避策略选择是一个复杂的问题。论文针对这一应用背景,主要讨论了两个方面的内容:1)开发实现了一个假目标舰对抗信号级仿真平台。该平台实现了末制导主动脉冲雷达的完整信号处理流程,并综合考虑了舰船和箔条的多种目标散射模型,以及风速、风向等多种环境因素的影响。2)针对一种静态测试方案,讨论了箔条干扰成功判定准则。在大量仿真统计的基础上,初步归纳了箔条布放和舰船规避的基本策略,并提出了"安全区域"的概念。仿真结果表明,根据当时的环境条件,如果保证箔条处在舰船的安全区域内,则对抗成功的概率将大大提高。Chaff jamming is one of the most important passive jamming means. In certain sea and environmental conditions, the chaff playing strategy and ship evading strategy is a complicated problem. This paper is aimed at this one application background, mainly discusses two aspects of content, including 1） a play naval against signal level simulation platform is built. This platform achieved terminal-guidance active pulse radar signal processing flow of complete, and considering the ships and chaff variety of target scattering model, and wind speed, wind direction and so on many kinds of environmental fac- tor influence. 2） To a static test scheme, the chaff jammming success criteria are discussed. On the basis of large simulation statistics, the paper summarizes the chaff cloth and ship evade the basic strategy, and puts forward the concept of ＂safety zone＂. Simulation results indicate that, if the chaff is in the safety zone, the probability of success will rise greatly according to the environmental conditions.
