该程序采用matlab编程，对相干源进行DOA估计，采用的Capon算法，Capon算法利用滤波器的思想，使某些特定频率的信号无失真地经过滤波器，而这些范围之外的则无法通过，进而进行DOA估计(The program using matlab programming, DOA estimation of coherent sources, USES the Capon algorithm, Capon algorithm using the ideas of filter, the specific frequency signal without distortion through the filter, while those beyond the range of the fail, then estimate the DOA)
