摘　　要：分析了箔条云团在自由空间的扩散方式,在箔条云扩散的"大爆炸"模型下,给出了箔条云在不同弹道阶段的有效干扰散射体积;然后,研究了箔条云团对防御雷达检测性能的影响,指出采用较优的战术使用可延迟雷达对目标的发现时机;再次,研究了箔条云团对雷达成像的影响,分析了箔条和噪声干扰效果的差别,并进行了相应的仿真实验;最后,提出了优化箔条干扰效果的几条战术建议。The diffusion mode of chaff cloud is analyzed for outer space. According to the ＂big Ban＂ model, the effective jamming volume of chaff cloud is presented for different trajectory phase. Secondly, the influence of chaff cloud on detection is discussed. It is pointed out that correct tactical application can delay the time for radar to detect target. Then, the influence of chaff cloud on high-resolution radar imaging is studied in detail. The jamming effect difference between chaff and noise is illustrated. The relevant simulation results are given. Lastly, several tactical scenarios are put forward for improving jamming performance of chaff cloud.
