说明：  研究了一种改进型的最小方差波束形成器。它在波束主瓣以外的其他方向上， 对波束形成器的响应作定积分。要求波束形成器输出功率最小的同时也要求这个 积分值最小。
(An improved minimum variance beamformer. It in the other directions outside the main lobe of the beam, the response of the beamformer definite integral. Minimum also requires the integral value of the minimum requirements of the output power of the beamformer.)
