摘　　要：天波超视距雷达在传播过程中会受到电离层的相位干扰,这将导致信号频谱的展宽,电离层的相位污染影响了雷达的探测性能。介绍分析了一种简单有效的去除电离层相位污染的方法,并进行了仿真研究。结果表明,该方法具有稳健的去污染效果。In sky-wave over-the horizon radar（OTHR）,radar signals are subjected to a variety of distortion and contamination effects as they propagate through the ionosphere,leading to severe degradation of the detection capability of OTHR radar.This paper introduces and analyzes a simple and effective method to decontaminate.Finally,the simulation examples are presented and the robust performance of this approach is demonstrated when the ionosphere slowly distorts.

关 键 词：天波超视距雷达 电离层 相位污染校正
