摘　　要：以高频地波雷达为背景 ,提出了三维极化向量滤波方法 ,此法能够滤除二维极化滤波不能滤除的干扰 ,综合提高极化域和空域的抗干扰能力。文中详细讨论了三维极化滤波参数的估计方法 。In this paper, an algorithm of three dimension polarization filtering is put forward in the background of HF ground wave OTH radar. The new technique can suppress the sky-wave interference which can not be handled in a two dimension polarization filter. Estimation of polarization parameters of the three dimensions polarization vector is discussed in detail and a simple method of parameter estimation is given out when the polarization degree of interference is very high.
