摘要：
A computationally efficient algorithm is herein proposed for estimation of the direction of arrival (DOA) of uncorrelated sources and for self-calibration of mutual coupling among sensors constituting several subarrays, with each subarray internally uniformly spaced. These subarrays may differ it! size but are identical in the orientation of their subarray-axes. Mutual coupling is herein modelled as independent of the incident sources. DOA identifiability is also investigated. Simulation results illustrate that the new algorithm possesses high resolution, low computational complexity and better accuracy of self-calibration.
