Abstract

A new millimeter-wave (MMW) radar target classification approach has been proposed using polarimetric information to obtain stable amplitudes of range profiles, and neural learning to extract angle invariant features of range profiles. The means of the polarimetric processing for reducing the speckle can enhance ability to discriminate targets. Compared with conventional approaches, the subclass features obtained carry more information due to the neural learning and thus make the correctness of target classification higher. The simulation results have verified the validity of this approach.

基于偏振高距离分辨率的雷达目标分类新方法
提出了一种新的毫米波(MMW)雷达目标分类方法,利用偏振信息获取距离像的稳定幅值,利用神经学习提取距离像的角度不变特征。采用极化处理的方法来减少散斑,可以提高对目标的识别能力。与传统方法相比,由于神经学习,获得的子类特征携带了更多的信息,从而提高了目标分类的正确性。仿真结果验证了该方法的有效性。
