产生一组信号，信号中含有多个目标信号，并对该组信号进行常规波束形成与MVDR波束形成，并进行相应的方位谱估计，使用文档对两种模型进行了充分的解释，对于理解方法的本质有很大的帮助(Generates a set of signals and the group signal by conventional beamforming and MVDR beamforming, and the corresponding range of spectrum estimation, use the document a full explanation of the two models are of great help to understand the nature of the method)
