说明：  MVDR是一种基于最大信干噪比（SINR）准则的自适应波束形成算法。MVDR 算法可以自适应的使阵列输出在期望方向上功率最小同时信干噪比最大。
(MVDR is an adaptive beamforming algorithm based on maximum signal-to-noise ratio (SINR) criterion. The MVDR algorithm adaptively minimizes the power of array output in the desired direction and the maximum signal to dry noise ratio.)
