论文摘要
稀疏的阵列最近吸引了许多兴趣，因为它们比传统的统一线性阵列提供了更多的自由度。对于圆形和非圆形信号的混合物，大多数现有的到达方向（DOA）估计方法基于各种均匀阵列。最近，开发了基于稀疏阵列的DOA估计算法，用于圆形和非圆形信号的混合物。为了进一步提高其性能，在这项工作中，提出了一种修改的算法，可以解决相同数量的信号，并提供仿真结果以验证其性能。
Sparse arrays have attracted a lot of interests recently for their capability of providing more degrees of freedom than traditional uniform linear arrays. For a mixture of circular and noncircular signals, most of the existing direction of arrival (DOA) estimation methods are based on various uniform arrays. Recently, a class of DOA estimation algorithms based on sparse arrays was developed for a mixture of circular and noncircular signals. To further improve its performance, in this work, a modified algorithm is presented, which can resolve the same number of signals, and simulation results are provided to verified its performance.
