弹道导弹目标的瞬态极化识别

Instantaneous Polarization Recognition of Ballistic Missile Targets

首先利用雷达目标的瞬态极化散射矩阵,从矩阵论的角度给出了雷达目标电磁散射特性的刻画方法;然后结合弹头类目标实测数据,提取了一阶特征量和二阶特征量等两个随弹头目标姿态不敏感的稳健特征参量.最后,采用最近邻识别方法研究了弹头类目标的分类与识别问题.

The problem of feature-extraction and recognition of ballistic missile targets is studied. Based on the instantaneous polarization scattering matrix of radar targets, descriptions of its electromagnetic scattering characteristics are presented using the matrix theory. The first and second order polarization measures of radar targets are then derived with measured data of warhead targets, which are insensitive to the pose of radar targets. Classification and identification of missile targets are studied through nearest neighbor recognition methods.
