Theoretical Analysis of Polarization Recognition between Chaff cloud and ship

Chaff is a kind of passive disturbance which is commonly used. 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 such as warship in polarization domain under the theoretical analysis of the polarization scattering cross section of chaff. In order to find target more exactly, non-linear polarization transformation and polarization smoothness were applied to process the polarization information of chaff and ship target. The resulting recognition was effective by simulation.
