mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)

说明：  matlab在数字信号处理中的应用。随着数字信号处理的发展，matlab可以非常方便的进行数字运算和逻辑判断。(matlab in digital signal processing applications. With the development of digital signal processing, matlab can be very convenient for digital computation and logic to judge.)
