摘　　要：从两个不同方面建立弹道导弹进动的数学模型,然后用时频分析方法给出微多普勒的分析结果,证明这两种建立弹道导弹进动数学模型的方法是等价的、正确的。根据不同微运动微多普勒时频分布的差异以及不同微运动微多普勒变化周期的不同,可以识别出真弹头和诱饵。这为弹道导弹防御中段弹头和其他轻重诱饵的识别提供了一个新的可靠的方法。The mathematics models oI precession oI ballistic missile are established in two different aspects, and the result oI micro-Doppler analysis is given by time-frequency distribution,which proves the two methods oI establishment oI precession model oI ballistic missile are correct and equivalent. Based the difference oI micro-Doppler time-frequency distribution and periods oI different micro-motion,the warhead and decoys can be recognized,h provides a new and dependable method for warhead and decoys recognition in middle ballistic missile defense.
