摘　　要： 基于复数干涉质量与相干系数之间的关系,本文提出了一种基于相干系数指导的自适应滤波新方法。通过实验表明,相干系数指导的自适应滤波方法,在数据一致性、细节信息保持和边缘信息保持方面明显优于传统方法,相比之下去除噪声能力有所下降,残差点数目相对于固定窗口(大窗口)滤波较多,但是由于这种方法考虑了干涉噪声与相干系数之间的关系,所以滤波更符合实际,滤波综合性能较好。 Based on the relationship between complex interference quality and coherent coefficient, a kind of new method is put forward based on coherent coefficient guidance. The experimental results showed that the data consistency, detail in- formation keept and edge information is better than the traditional method by using this new method, contrasted with that, the ability of removing noise has dropped, the number of residual points is more than fixed window filtering（big window）, but because the relationship between interference noise and coherent coefficient is considered in this method, this mathod is more suitable to the actual, filtering comprehensive performance is good
