Abstract

A Khatri-Rao (KR) product based method for direction-of-arrival (DOA) estimation using uniform linear array (ULA) in the presence of mutual coupling is presented. Based on the fact that mutual coupling matrices of ULAs can be modeled as banded complex symmetric Toeplitz matrices, a cost function with the form of KR product is derived. An alternating minimization procedure is employed to estimate the DOAs of all the radiating signals as well as the mutual coupling coefficients and the power of signals. Simulation results that demonstrate the validity of the proposed method are included.
