Wide-band signal direction of arrival estimation methods for uniform circular arrays without sources number
针对未知信源数目下的宽带信号DOA估计问题，论文提出了一种未知信源数目的相干信源宽带DOA估计算法，算法使用聚焦变换和窄带高分辨率算法，在接收端使用均匀圆形阵列，完成了对宽带信号源的一维和二维DOA估计。通过计算机的仿真分析，该算法具有良好的性能和鲁棒性。
his paper presents a direction of arrival (DOA) estimation algorithm for wide-band signals, where the number of sources is unknown. The algorithm use focusing transform and narrow-band DOA algorithm with super resolution. When using uniform circular array（UCA）as the receiver, the 2D-DOA estimation can also be done with the algorithm. Simulation results show that the proposed algorithm performs good in direction finding ability, angle separation ability and similar RMSE.
