摘　　要：ORPD算法是一种对来波方向(DOA)估计的最佳分辨方法,但这种算法需要预知信源的大致方位。多信号分类(MUSIC)算法对DOA估计稳定性较好,伪峰情况基本不存在,精度较高,但其分辨能力不如ORPD算法。利用MUSIC算法较好的稳定性,首先预测信源的大致方位,然后利用ORPD算法对DOA进行估计。仿真结果表明,这种方法是比较有效的。ORPD algorithm is the best resolving method for estimation of DOA, but it needs to prior know the rough direction of the signals. blUSIC algorithm is characteristic of good stability, few pseudo - spectnnnpeaks and high precision, but its resolving power is weaker than ORPD algorithm. In this paper we first get the rough direction of the signals by MUSIC algorithm, and then estimate the DOA of the signals by ORPD algorithm. Simulative result verifies that this method is feasible.
