高频地波雷达海杂波背景下目标检测研究综述

A review of research on target detection in the background of high frequency ground wave radar and sea clutter

高频地波雷达探测距离远、全天候、实时准确探测等优点在目标检测领域广泛应用。针对海杂波会干扰目标检测的问题,分别从非线性预测类、分形类、子空间分解类、对消类等方面对海杂波背景下目标检测方法进行了综合评估。归纳总结国内外相关文献,并对目前方法存在的不足进行总结。为以后深入研究海杂波干扰问题提供参考。

The advantages of high-frequency ground wave radar with long detection range,all-weather,and real-time accurate detection are widely used in the field of target detection.Aiming at the problem that sea clutter can interfere with target detection,this paper comprehensively evaluates the target detection method in the background of sea clutter from the aspects of nonlinear prediction,fractal,subspace decomposition,and cancellation.Summarize relevant domestic and foreign literature,and put forward the prospects of the current methods.It provides a reference for further research on the problem of sea clutter interference in the future.
