Allan方差，可确定最佳积分时间，最小探测灵敏度-Allan variance, can be integral time, minimum detection sensitivity

小波变换和二维最大类间方差法实现变化检测-Wavelet transform and two-dimensional maximum between class variance method to achieve change detection

MVDR，又叫最小方差无失真响应估计，一维DOA估计，矢量阵，多目标，振元数，频率，信噪比都可以改-MVDR uFF0C u53C8 u53EB u6700 u5C0 u65B0 u5D9 u65E0 u5931 u771F u54CD u5E94 u4F30 u8BA1 uFF0C u4E00 u7EF4Dea u4F30 u8BA1 uFF0C u77E2 u91CF u9635 uFF0C U591A u76EE u6807 uFF
