中文说明：
传统的相控阵雷达，发射信号完全相关，通过对每个阵元加不同相移就可以改变波束的发射方向。以这种方式形成的波束通常主瓣较窄，信噪比比较高，若用于跟踪方向先验已知目标或只对空间某一窄的领域进行搜索时非常有利。本代码可以实现正交波束的形成.
English Description：
In traditional phased array radar, the transmitted signals are completely correlated, and the transmitting direction of the beam can be changed by adding different phase shift to each array element. The main lobe of the beam formed in this way is usually narrow and the signal-to-noise ratio is high. It is very advantageous to track the target with known direction a priori or search only in a narrow space. This code can achieve orthogonal beam forming
