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。

关键词: 同频干扰, 航海雷达, 海杂波, 溢油监测

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.

Key words: co-frequency interference, marine radar, sea clutter, oil spill monitoring
