摘要

摘要: 电离层相位污染严重制约天波超视距雷达对低可探测慢速舰船目标的检测性能，时频校正法成为目标检测的重要手段，对其进行分类并选取6种典型方法进行了去污染的综合性能评估。首先分析了性能比较的影响因素，然后从去污染的有效性、鲁棒性和运算量等几个方面进行了校正方法的综合比较。为电离层相位污染校正算法库的丰富和实际工程应用提供参考。

Abstract: Ionosphere phase contamination seriously restrains the detection performance of Over-The-Horizon Radar (OTHR) for low detectable targets, such as slow ships, and approaches of time-frequency correction are proposed and classified for effective target detection. A comprehensive performance evaluation of six typical approaches of time-frequency correction based on the key factor analysis of performance comparison is carried out in terms of decontamination effectiveness, robustness analysis and the computational load complexity. This research is of great reference for further development of ionosphere phase decontamination algorithm library and the practical engineering implementation.
