天波超视距雷达电离层相位污染典型校正方法综合性能评估

Performance Evaluation of Ionospheric Phase Contamination Correction Approaches for Over-the-Horizon Radar

对校正天波超视距雷达电离层相位污染的五种典型方法进行了综合性能评估,主要从校正效果、对不同污染的普适性、污染参数变化对方法的影响、信噪比对方法性能的影响、运算量等几个方面进行了比较与分析,为实际工程实现和改进电离层相位污染校正方法提供参考。

A comprehensive comparison of the existing ionosphere phase contamination correction approaches for sky-wave Over-the-Horizon Radar（OTHR） is made,and is evaluated from the view of correction efficiency,the universality of correction methods on different contaminations,the impact of phase contamination parameter change on approaches,the impact of SNR（signal-to-noise ratio） change on approaches and computational loads.The research lays the foundation for the practical engineering implementation and the improvement for the contamination correction methods.
