摘要

摘要: 针对现有的长基线旋转干涉仪存在相位模糊，且不能对多个同频、同时到达的目标信号进行角度估计问题，该文提出一种基于旋转干涉仪虚拟圆阵化的多目标波达参数估计新算法。该方法首先将旋转干涉仪采样得到的两通道数据进行共轭相乘操作，获得虚拟圆阵信号；然后采用波束空间变换法将虚拟圆阵数据从阵元空间转换到波束空间，得到虚拟线阵数据序列；最后在实波束域上实现多目标2维角度无模糊估计。相比于传统旋转干涉仪方法而言，所提方法在不增加接收通道的同时，能够实现多目标角度的无模糊测量。仿真实验验证了所提方法的有效性。

Abstract: Focus on the problem of phase ambiguity and the issue that it is impossible to estimate the unambiguous angles of multiple sources with the same frequency and time of arrival. An approach for multiple sources parameters estimation with rotating interferometer using virtual circular array processing is proposed in this paper. Firstly, the virtual circular array data is constructed by taking conjugate multiplication of the two channel data received by the rotating interferometer. Then, the virtue linear array data is obtained by employing beamspace transformation, which performs mapping from element-space to beamspace domain. Finally, the unambiguous angles of the multiple emitters are achieved in beamspace domain. Compared with conventional rotating interferometer methods, the proposed method can deal with the problem of unambiguous Direction Of Arrival (DOA) estimation of multiple emitters with only two receiving channels. The validity of the proposed method is verified by the simulation results.
