摘要(Abstract)：

为了探究中值滤波与加权滤波方法对测深数据粗差的处理效果,该文以单波束测深数据为例,对中值滤波和加权滤波在不同大小滤波窗口的测深数据处理效果进行对比分析。实验结果表明,中值滤波不论在地形起伏变化较快的区域,还是在少量、断点不连续的区域以及大量、断点连续的区域,均具有较好的滤波效果,且在5窗口时效果最佳;而加权滤波在地形起伏变化较快的区域以及少量、断点不连续的区域处理效果明显,且在3窗口时效果最佳,但中值滤波效果更优,而在大量、断点连续的区域加权滤波效果明显较差,建议优先考虑中值滤波方法。

关键词(KeyWords)： 单波束测深;粗差;中值滤波;加权滤波;滤波窗口
