## New method for single-snapshot two-dimensional direction of arrival estimation based on noncircular signals

• 摘要: 针对双平行线阵相干信号二维波达方向(DOA,Direction of Arrival)快速估计问题,利用信号的非圆特性,提出了一种基于非圆信号的单次快拍数据的二维DOA算法.建立新的阵列坐标系,对阵列接收单次快拍数据进行共轭运算,通过数据重新链接得到伪快拍数据,阵列孔径扩展1倍.仅需要对3个伪单快拍矩阵的扩展矩阵进行一次奇异值分解即可实现二维DOA估计和解相干.该算法计算复杂度低,估计精度高,适用于对二维DOA估计实时性要求高的应用背景.计算机仿真结果验证了方法的有效性.
