计算按频率抽取的基4快速傅里叶变换算法，与基2FFT相比，基4FFT的乘法量约减少25 。(Calculating frequency taken by fast Fourier transform algorithm base 4, compared with the base 2FFT the base 4FFT multiplication about 25 less.)

阵列处理作业，MVDR或者其他高分辨方法，由于信号源无法确定，造成估计误差，采用对角加载的 增加单位阵法 ,以及 六源准则法 获取优化结果。(Array processing, MVDR, or other high-resolution method, the source can not be determined, resulting in the estimated error, the use of diagonal loading ' to increase the unit matrix method' , and ' six-source criteria method' to obtain optimal results.)

说明：  基于欧拉距离的KNN分类器，可自行调节map和预测点的位置。运行时首先显示分布散点图，之后输出预测值(Here is a KNN classifier based on Euler distance with self-adjusting map and prediction point positions. The distribution scatter will plot displayed map at first, then show the predicted value.)
