摘要：In this paper, the one-dimensional direction of arrival estimation problem for a mixture of circular and noncircular sources is considered. We call this algorithm Mixed-PM algorithm, which is based on classical PM algorithm. Firstly, we introduce the concept of circular and noncircular signals. And then we explain the theory of Mixed-PM algorithm in detail, which is able to distinguish circular signals and noncircular signals in mixed signals. We find that the performance of Mixed-PM algorithm is better than classical PM. In addition, we also studied the performance of Mixed-PM algorithm under different snapshots and different received array elements. Finally, we study the influence of the number of different round signals on the performance of the algorithm, find that the smaller the number of round signals, the better the performance of the algorithm.
