Abstract

A novel polarization filtering method based on the oblique projection operator is proposed to improve the target detection performance for High Frequency Surface Wave Radar (HFSWR) system in this paper. The performance of the proposed oblique projection polarization filter (OPPF) is detailedly analyzed in presence of additive Gaussian white noise and the desired signal´s Mean Square Error (MSE) with the estimation error of the interference polarization parameter is discussed in detail. Numerical simulation results show that the proposed OPPF can enhance the target while mitigate the interference perfectly.
