波束空间DOA的估计,从图中可以很好的看出角度的估计还是可以的。-Beam-space DOA estimation, from the figure we can see the point of a good estimate is still possible.

OMP算法应用在DOA估计，可以分辨多个目标，估计出目标方位，且有很高的分辨性能。-OMP algorithm used in DOA estimation, can distinguish multiple targets, to estimate the target orientation, and have a high resolution performance.
