摘要
采用自适应极化滤波来克服同方位、同频率信号对地波超视距雷达的干扰，需要一个正交的双极化接收天线系统。本文给出了由地波超视距雷达接收天线阵和一个水平对称短振子天线构成的正交双极化天线，并讨论了在理想地面情况下，以接收天线阵中心为坐标原点时。
An orthogonal polarization receiving antenna system is needed to eliminate the inter- ference of the same direction and frequency to ground wave over-the-horizon radar(GW-OTHR)by adaptive polarization filter.This paper gives an orthogonal polarization antenna composed of re- ceiving antenna array of GW-OTHR and a horizontal short symmetrical dipole,And it discusses the directivity function of antenna with ideal ground based on the center of array as coordinate origin.
