Direction-of-Arrival Estimation and Sensor Array Error Calibration Based on Blind Signal Separation

Abstract: We consider estimating the direction of arrival (DOA) in the presence of sensor array error. In the proposed method, a blind signal separation method, the Joint Approximation and Diagonalization of Eigenmatrices (JADE) algorithm, is implemented to separate the signal vector and the mixing matrix consisting of the array manifold matrix and the sensor array error matrix. Based on a new mixing matrix and the reconstruction of the array output vector of each individual signal, we propose a novel DOA estimation met… Show more

“…In this method, the sensor locations are assumed to be known, and the gain and phase calibration errors of the sensors are estimated. Similarly, the signal estimation and the blind sensor calibration are performed separately in [32]. In [33], a blind calibration method using independent component analysis is studied which considers the gain and the phase errors for a linear array.…”

“…The covariance matrix does not contain the phase error, so the subspace algorithm can be directly used to estimate the direction of the signal source. In References [ 37 , 38 ], the relationship between the gain-phase errors and the array manifold vector is established to eliminate the errors in MUSIC spatial spectrum, Then the DOA of two calibration sources is estimated by two-dimensional spatial spectrum search. The algorithms in References [ 35 , 36 , 37 , 38 ] do not need iteration, and the estimation performance is independent of the phase error.…”
