强海杂波背景下目标检测方法综述

Review on target detection in the background of strong sea clutter

摘要:

高频地波雷达被广泛应用于海面目标的检测，而由于海杂波的分布散射具有很强的动态特性，通常情况下成为了海面目标检测的主要干扰成分。因此，在强海杂波背景下进行目标检测的关键在于如何有效抑制海杂波。从循环对消、子空间分解、模型预测以及分形特征这几方面对海杂波抑制技术进行综述、分析和总结，为后续对海面目标检测提供参考。

Abstract:

High-frequency ground wave radar is widely used in the detection of sea targets, and sea clutter has stronger dynamic characteristics due to distributed scattering, and usually becomes the main interference component of sea target detection. Therefore, the key to target detection under the background of strong sea clutter is how to effectively suppress sea clutter. This article summarizes the sea clutter suppression technology from the aspects of cyclic cancellation, subspace decomposition, model prediction and fractal features to provide a reference for subsequent sea surface target detection.
