【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]:At the same time , the method of convolution operation is applied to divide the same - frequency interference noise signal in the original data of the navigation radar by using the convolution operation method . At the same time , the transverse - mean - means algorithm is applied to deal with the same - frequency interference noise . The method has the advantages of retaining the wave clutter signal containing the oil spill information while reducing the noise reduction process on the same - frequency interference , and providing more accurate basic data for the research of the oil spill monitoring technology of the navigation radar .
