中文说明：欢迎大家下载学习，利用自然梯度算法，考虑雨衰 阴影 和多径影响，进行波形数据分析,粒子图像分割及匹配均为自行编制的子例程，应用小区域方差对比，程序简单。
English Description：
Welcome everyone to download to learn, by using the natural gradient algorithm, consider rain attenuation shadowing and multipath effects, waveform data analysis, particle image segmentation and matching are self-made subroutine, application of small regional variance contrast, the program is simple.
