摘要

本文提出了新的高频地波超视距雷达抗非平稳射频干扰解决方案

以改善高频雷达中目标检测的性能.本文首先给出一种利用微调波束指向的导向矢量

在允许的误差范围内最大程度抑制干扰的最优算法

然后本文根据基于海杂波保持的思想提出一种新的算法解决近距离海杂波扩散引起基底抬高的问题.最后本文总结了两种算法相结合的统一方案

实验数据处理结果都表明这一方案对抗非平稳射频干扰是有效的.

Abstract

A novel nonstationary radio interference cancellation scheme was given to improve the performance of target detection in high frequency surface wave Over-the-Horizon radar.First

the optimum algorithm was proposed that suppresses the nonstationary interference to the utmost by modifying the array steering vector under the permitted error limit;then

a method based on the idea of maintaining the sea clutter response was introduced to settle the problem of floor increasing for the reason of the clutter scatter.The interference cancellation frame was synthesized by the two methods at last.And the experimental results show it is efficient to reject the nonstationary interference.
