摘要
高频地波雷达能够对海上目标实现超视距、全天候的探测,目前已经成为海上动目标检测的重要手段。但在复杂的海洋环境下,目标信号受海杂波影响较大,对海杂波进行有效抑制成为精确检测目标的关键。首先介绍高频地波雷达海杂波的形成机理,然后分别从对消类、小波变换类和子空间类三个方面对海杂波抑制方法进行综述。最后对现有方法存在的不足进行总结并展望未来研究的方向。通过综述为高频地波雷达海杂波抑制提供重要参考。
High frequency ground wave radar has the ability to detect marine targets beyond visual range and all weather. At present, it has become an important means of moving target detection at sea. However, in the complex Marine environment, the target signal is greatly affected by sea clutter, and the effective suppression of sea clutter becomes the key to the accurate detection of targets. First, the formation mechanism of sea clutter of high frequency ground wave radar is introduced, and then summarizes the sea clutter suppression methods from three aspects: cancellation, wavelet transform and subspace. Finally, the shortcomings of the existing methods are summarized and the future research directions are prospected. This paper provides an important reference for sea clutter suppression of high frequency ground wave radar.
