中文说明：在信号DOA估计中，通常涉及到信源信号路径的交叉，或是信号的角度分辨率分辨不高，在这种情况下，基于压缩感知的DOA估计怎么处理呢？对于信源信号的重定位和预处理，增强信噪比等处理。
English Description：
Signal DOA estimation, usually involves the source signal paths crossed, or angle resolution of signal resolution is not high, in this case, compressed sensing based DOA estimation how to deal with it? For relocations and preprocessing of source signals, enhanced signal to noise ratio.
