分析了目标特性和海杂波特性，分析了在强海杂波干扰背景下检测潜望镜的一种方法，着重叙述了三维滤波器－检测前跟踪的处理方法和抑制海杂波的原理，给出了仿真及试验结论。

Target and sea clutter characteristics are analyzed. A method of detecting periscope against the background of strong sea clutters is introduced. A processing method and the principle of restraining sea clutter of three-dimensional filter, that is tracking-before-detection, are emphatically described. Simulation and test results are given.
