Algorithm on High Resolution DOA Estimation without Sources Number
一种未知信源数的高分辨DOA估计算法

Many of the super resolution DOA(Direction-Of-Arrival) estimation algorithms presume the number of signal sources. Since the sample snapshot is limited, however, the available algorithms on source number estimation may fail at lower SNR. In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be viewed as a combination of merit of conventional Capon and MUSIC method. The algorithm’s feasibility and robustness are analyzed and verified by the simulation and actual experiment data.
