基于微多普勒分析的弹道目标识别技术研究

目标微动产生的微多普勒特征,通常被认为是目标独有的特征,可用于确定目标的性质,实现对目标的检测、识别与分类。文中在对微动目标微多普勒分析的基础上,建立了导弹与诱饵的数学模型,采用短时傅里叶变换的方法对回波信号进行微多普勒特征提取,仿真分析了导弹与诱饵的微多普勒特征,通过研究其时频分布特点的差异成功的识别出了真假目标,从而为弹道导弹与重诱饵的识别提供了一个新的有效方法。

Research on the Discrimination of the Ballistic targets Based on Micro-Doppler analysis

The characteristic in targets micro-doppler that derives from the micro-motion of the target is generally unique.Consequently,it can be utilized to automatic target recognition and classification.In this work,based on the principle of micro-doppler,the mathematical model between missile and decoy is constructed,and characteristics in micro-doppler are analyzed through simulation,thus distinguishing the target from heavy decoys and the missile.It offers a new reassuring way to the discrimination of the real ...
