Echo theoretical analysis from chaff cloud and research polarization targets recognition

Chaff is a constantly used method of passive disturb, and it is difficult to find an efficient method to depress and recognize chaff in both time and frequency domain. This paper tries to recognize chaff and target like warship in polarization domain under the theoretical analysis of the polarization scattering cross section of chaff. In order to find target more exactly, methods of non-linear polarization transformation and polarization smoothness were applied to process the polarization information of chaff and ship target. The resulting recognition was notable by simulation.
