摘要：

This paper focuses on the direction of arrival (DOA) under the circumstance of mixed circular and noncircular sources with Minimum-Redundancy Linear Array(MRLA). By exploiting receiving signal data and its conjugate, the proposed algorithm can augment the maximum number of detectable sources. Using the weighted MUSIC algorithm during the whole space, the proposed scheme can obtain perfect quality for MRLA without knowing the number of sources. Simulation results clearly show that the effectiveness of our proposed algorithm.
