Passive radar polarisation filtering technology research

Abstract

This study researches the potential benefits of clutter suppression in polarisation filtering technology. In the author's laboratory, the antenna of the experimental system has been designed, called dual-polarised Yagi-Uda antenna and the antenna can receive both horizontal and vertical polarisation simultaneously. The experimental results show that the method of improved polarisation filtering can suppress the clutter effectively, which is composed of direct-path signal and multipath clutters.
