常用的CINRADSASB雷达基数据格式，已经将反射率数据读入ref[rads][gates]数组中，其中rad和gate分别为径向数和库数，绘成常见的天气雷达回波图像-Common data format CINRADSASB Lei Daji, the reflectance data has been read into the ref [rads] [gates] array, which was rad and the radial gate number and library nu

输入灰度图片的中心坐标点，和要计算的半径。计算出圆心坐标所有圆环的半径上圆的灰度均值，返回一个矩阵-input the circle center, and the rad output the circle ring gray

matlab混合编程，实现了ＲＡＤ图像处理的接口处理代码，然后进行编译为库文件，方便在ＶＣ中调用处理。(Matlab hybrid programming, the implementation of the RAD image processing interface processing code, and then compiled into a library file, convenient to call in the VC processing.)
