摘要：
In this paper, we consider the problem of direction finding in partly calibrated uniform linear array (ULA) system with channel gain/phase mismatch, by taking advantage of the high-order statistics (HOS) of the array observations. In particular, we devise a (2M - 1) x (2M - 1) fourth-order cumulant (FOC) matrix for an M-element ULA and exploit it to estimate the directions-of-arrival (DOAs) with subspace techniques. The proposed FOC direction finding method is computationally attractive without spatial spectrum search and robust against spatially correlated noise. It is also able to achieve better DOA estimation performance than the existing method, as illustrated by numerical simulations. (C) 2019 Elsevier B.V. All rights reserved.
