采用10阵元的阵元间距为1/2波长的均匀线阵，估计2个不相干的信号源的波打方向。其中样本数为100，S/N分别为10dB，20dB。信号源来自-10°和40°。程序里面包含用MUSIC,RootMUSIC，ESPRIT,MVDR,F-SAPES算法实现的DOA估计-A 10-element array element spacing of 1/2 wavelength of the uniform linear array, it is estimated that two unrelated source wave hit direction. Wherein the number of samples is 100, S/N of 10dB, 20dB, respectively. Source from-10 and 40. DOA estimation program inside contains MUSIC, RootMUSIC, ESPRIT, MVDR, F-SAPES algorithm implementation
