| 摘 要： | 首先提出了在平面坐标下进行航海雷达同频干扰噪声处理；再采用卷积运算方法和Otsu算法分割航海雷达原始数据中的同频干扰噪声信号；最后应用横向均值运算方法处理同频干扰噪声。这种处理方法在对同频干扰进行降噪处理的同时，保留了含有溢油信息的海浪杂波信号，为航海雷达溢油监测技术的研究提供了更为准确的基础数据。

| Abstract: | The marine radar co-frequency interference noise should be processed in the plane coordinate system.Then the convolution algorithm and Otsu algorithm are used to segment the co-frequency interference noise signal in the original data of marine radar.At last,the method of horizontal mean is used to deal with the co-frequency interference noise.This method can reduce the noise of the co-frequency interference noise and preserve the clutter signal.It provides more accurate basic data for the research of oil spill monitoring technology. |

| Keywords: | co-frequency interference marine radar sea clutter oil spill monitoring |
