摘　　要：为了有效提高稀薄空气下太空箔条抛撒的使用效能,针对箔条的运动特点和雷达探测特性,建立了高空箔条扩散运动模型和多雷达探测区下的弹载箔条有效抛撒时间区间模型。对特定时间区间抛撒箔条的运动过程进行了数值仿真,得到了抛撒时间对箔条干扰效果的影响。建立基于雷达重要性的不同抛撒区间策略并进行了讨论。得到了不同要求下箔条的有效抛撒时间区间。研究结果表明:箔条云团抛撒时区的变化显著影响箔条工作效能;调整箔条抛撒时刻,可以满足箔条云团工作的不同任务要求。The diffusive movement and effective dispersion time interval models in multi-radar environment are established to improve the utility efficiency of outer space chaff dispersion in the thin air according to the movement characteristics of chaffs and the detection performance of radar. The numerical calculation about the chaff movement process dispersed at a specific time interval is carried out,and the influence of chaff release time on jamming effect is obtained. The different dispersion time interval strategies based on radar importance are discussed,and the effective dispersion time interval strategies under different conditions are proposed. The results indicate that the variation in dispersion time interval of chaff cloud has a great influence on the chaff working efficiency and the different mission requirements can be met by adjusting the dispersion time.
