| 摘 要： | 弹道目标的结构特征反映了目标的本质属性,是识别真假目标最直观的特征之一。分析了弹道目标的结构特征差异,系统归纳了基于结构特征的弹道目标雷达识别方法。根据雷达提取结构特征所采用的信息不同,将这种识别方法分为基于RCS序列的识别方法、基于一维像的识别方法、基于二维像的识别方法以及基于极化信息的识别方法,详细阐述了这四类识别方法的物理基础及其实现途径,分析了它们各自的特点,最后展望了技术发展趋势。

| Abstract: | Configuration feature reflects the property of ballistic targets and can be taken as the intuitionistic feature for alleging fraud.The configuration feature difference between warhead and decoy is analyzed.According to the used feature,the recognition methods based on configuration feature are divided four categories,namely,recognition method based on RCS sequence,recognition method based on high resolution range profile feature,recognition method based on inverse synthesis aperture image and recognition method based on polarization information.The physics foundation of four methods is expounded and their traits are discussed respectively.Finally,the future tendency of those techniques is prospected. |
