主要研究了利用雷达目标RCS序列提取弹道导弹进动周期的方法。首先建立了弹道导弹中段目标的进动模型,分析了目标RCS回波数据与进动周期的关系表达式,然后给出了利用目标RCS序列估计进动周期的方法。仿真实验结果表明,文中提出的方法能够有效估计目标的进动周期。

A method of extracting the precession period of ballistic missiles(BM) in the Midcourse Phase of their ballistic trajectories with radar cross section(RCS) sequence was presented.The motion of ballistic missiles in the Midcourse Phase was analyzed and modeled.Then the relationship between the precession period of missile warhead and its RCS sequence was discussed.Based on the variation characteristics lying in the RCS sequence,a method of extracting the precession period was proposed.Simulation results demonstrated the efficiency of the method.
