Target polarization recognition under rain and snow cluster

This paper derived the polarization scattering matrix of both warship target and interferential chaff conditioned on the exit of rain and snow cluster, and furthermore, proposed a method to recognize chaff and warship by analyzing their corresponding polarization information. This method mainly aims to radar, which can receive both left and right circularly polarized wave, to catch the full polarization information of echoes, then, acquires the more accurate polarization characteristics of target and chaff after getting rid of the impacts of rain and snow cluster from the polarization scattering power matrix of echoes. In order to further improve the recognition probability, non-linear polarization transformation is introduced to make the separation of target and chaff more realizable. It indicates that the resulting performance is incredible for the traditional recognition in time and frequency domain
