Abstract	In dynamic electromagnetic environments, a polarization estimator is usually utilized by an adaptive polarization filter to acquire the knowledge of the polarization of the interference field, then optimal polarization is calculated for the polarization filtering. In this sense, an adaptive polarization filter can be modeled as an open loop cascading system of a polarization estimator, an optimum polarization calculator and a polarization filter. Based on dual channel orthogonal polarization measurements, a theoretical performance analysis of the polarization estimator is derived. It is proved that the polarization estimation error obeys the Rayleigh distribution, approximately. Finally, by studying the transmission process of the estimation error in a polarization filter, a series of analytic formulae on the performances of adaptive polarization filters are derived, which statistically reveal the relationship between the filtering performance and the signal to noise ratio clearly.
