| 摘 要： | 天波超视距雷达中，电离层的各种失真和污染恶化了散射回波信号的性能，海杂波Bragg峰的展宽和分裂几乎淹没了微弱的舰船目标。本文分析了电离层失真的形成机理，并对几种失真校正方法进行了分析和比较，对工程中提高舰船目标的检测能力具有重大的现实意义。

| Abstract: | In Sky-wave Over-the Horizon(OTH)Radar, the distortion and contamination of ionosphere degrade the performance of the backscattered signals greatly. The weak ship target is almost masked by the spreading and splitting for Bragg peak. This paper describes the mechanism of ionosphere distortion and several correction algorithms. It is important for the improvement of ship target detection in practice. |
