摘要

本文提出了采用三维正交极化接收天线对高频地波雷达天波干扰进行极化滤波的方法

此法能在极化域和空域综合抑制二维正交极化滤波不能滤除的干扰.为了进一步提高抗干扰能力

文中给出了

分量最佳实数加权法

理论证明这种加权法可以减小极化损失、有效提高滤波器输出SINR、扩大极化域和空域内的干扰抑制范围.

Abstract

A method of suppressing HF sky-wave interference in ground wave OTH radar is put forward

in which three dimension orthogonally polarized receiving antennas are utilized.The new technique can suppress the sky-wave interference which can't be handled in a two dimension orthogonal polarization filter.In order to further improve the interference suppression ability

an optimum weighting method is given.It is proved in theory that the weighting method can effectively decrease polarization loss

increase output SINR and enlarge interference suppression area in polarization domain and space domain.
