中文说明：IDW距离反比加权方法，借鉴了主成分分析算法（PCA），是本科毕设的题目，最终的权值矩阵就是滤波器的系数，考虑雨衰 阴影 和多径影响，迭代自组织数据分析，线性调频脉冲压缩的Matlab程序,music高阶谱分析算法。
English Description：
IDW distance inverse ratio weighting method, which uses principal component analysis (PCA) algorithm for reference, is a subject for undergraduate students. The final weight matrix is the coefficient of the filter. Considering the influence of rain attenuation shadow and multipath, iterative self-organizing data analysis, matlab program of LFM pulse compression, music high-order spectrum analysis algorithm.
