| 摘 要： | 通过微多普勒可以提取弹道导弹目标的微动特征,利用弹头和诱饵微动特征的差异可识别出真弹头.运用角动量守恒定理分析了弹道导弹目标在各阶段的微动形式,运用叉乘矩阵、泰勒级数等原理,推导出了弹道导弹目标的微动模型,给出了弹道导弹目标的微多普勒计算公式,从理论上分析了其微多普勒特征.利用时频分析方法从回波信号中提取了弹道导弹目标的微多普勒,从回波信号中提取的微多普勒与理论上计算的微多普勒一致,表明分析方法有效,结论正确.

| Abstract: | The real warhead may be discriminated by micro-motion difference of warhead and decoys extracted by micro-Doppler of warhead and decoys.The micro-motion form of ballistic missile targets during each phase is analyzed by the angle momentum conservation,and the micro-motion model of ballistic missile targets is deduced with the principle of cross matrix and Thaler series.The micro-Doppler formula of ballistic missile targets is derived and the micro-Doppler signatures are analyzed.The micro-Doppler extracted from the echoes of ballistic missile targets by means of time frequency representation is consistent with the theoretical micro-Doppler values,indicating the micro-motion model mentioned in this paper is effective and the conclusion is exact. |
