摘　　要：建立雷达导引头模型和箔条云扩散、RCS仿真模型,研究箔条云扩散特征与RCS随时间变化规律;依据相关文献计算直升机RCS特性,建立雷达导引头、箔条云和直升机之间的对抗模型,在不同作战场景下进行箔条弹作战使用和干扰效果研究。研究结果表明,在前下方或后下方攻击时,投放策略为投放2发;在正侧方攻击时,投放策略为分组投放、每组4发、2发齐射。The radar seeker model,chaff cloud diffusion and RCS simulation model are established.The change rule of chaff cloud diffusion characteristicsa and RCS over time is studied.Helicopter RCS characteristic according to relevant lierature is calculated,and countermeasure model of radar seeker,chaff cloud,helicopter is established.The operational use and interference effectiveness of chaff bombs are studied in different scenarios.The result of research shows that launch strategy is two shots when attacting from above or below. The launch strategy is group placement,four shots per group,and double per time when attacting from abeam direction.
