摘要

为了提高高频表面波雷达对干扰的抑制能力，利用2000年生产的OSMAR2000海洋状态监测与分析雷达的子阵列，对自适应抗干扰技术进行了研究。本文提出了在不增加任何辅助设施的情况下，在OSMAR2000雷达基础上抑制外部高频无线电强干扰的方案，并以单极子为主天线，其他三个垂直单极子为辅天线进行了雷达实验。本文介绍了一种抑制强干扰的子阵列自适应系统的初步研究结果。研究结果表明，该技术能够很好地抵抗观测到的干扰。

A method for adaptive anti-interference based on subarrays in HF ground wave radar

To improve the capability of high frequency (HF) surface wave radar to suppress interference, an adaptive anti-interference technique was evaluated by using subarrays in OSMAR2000 (ocean state monitor and analysis radar, manufactured in 2000). In this paper, we put forward a scheme to suppress the external HF radio strong interference based on OSMAR2000 radar without increasing any accessional facilities, and some radar experiments were carried out by using a monopole as main antenna and other three vertical monopoles as auxiliary antennas. This paper presented the results of a preliminary study of an adaptive system with subarrays for the suppression of strong interference. The results of the study show that the technique worked well against the observed interference.
