波束形成就是从传感器阵列重构源信号。（1）、通过增加期望信源的贡献来实现；（2）、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复。 波束形成技术的基本思想是：通过将各阵元输出进行加权求和，在一时间内将天线阵列波束“导向”到一个方向上，对期望信号得到最大输出功率的导向位置即给出DOA估计。 虽然阵列天线的方向图是全方向的，但阵列的输出经过加权求和后，却可以被调整到阵列接收的方向增益聚集在一个方向上，相当于形成了一个”波束”。这就是波束形成的物理意义所在。 ()

说明：  w-w1各教徒和w1个非教徒在海上遇险，必须将一半的人投到海中，其余的人才能幸免，于是想了个办法w人围成一圈从第一人开始报数，数到第w2个就将其人丢入海中，又从下个人数，数到第w2个人又丢入海中，依次循环，怎样排才使投入大海的都是非教徒(w-w1 and w1 of all non-believers believers in distress at sea, half of them must be invested in the sea, the others can be spared, so think of one way to w people form a circle from the first people began to count off a few to the first w2 one would be thrown into the sea of its people, and from under the personal number, the number of individuals to the first w2 then thrown into the sea, followed by recycling, how to make it into the sea row are non-believers)

说明：  给定一幅图象，输出其直方图； 通过对话框给定一个线性变换函数，实现图象的灰度拉伸； 实现对图象的均衡化。 (Given an image, the output of its histogram dialog given by a linear transformation function to realize the gray scale image stretching to achieve the equalization of image.)
