摘要
常规的弱点目标检测算法在背景边缘如海天线、云层和海浪边缘会形成高的虚警。通过对背景边缘梯度的分析后发现,背景边缘与弱点目标在多向梯度特性上存在差异,据此提出了一种背景杂波抑制新方法。
Background clutters, such as the sea-horizon, high false alarm to detect dim between dim-point targets an -point targets by normal algorithms. d background clutters by analysis. brims of clouds and There is a difference A new algorithm is ocean in the presen waves, cause grad character ted to remove background clutters based on the difference.
