Abstract

In array signal processing, high-resolution direction-of-arrival (DOA) estimation algorithms are known to be sensitive to system errors. In practice, the system should be properly calibrated before DOA estimation. In this paper, a multidimensional calibration method of gain and phase errors of uniform circular array (UCA) based on the weighted subspace fitting (WSF) scheme is proposed in the presence of multipath propagation. Simulation results are provided to demonstrate the performance of proposed algorithm.
