【 摘 要 】

Gain-phase errors calibration is important for systems using sensor array. In this paper, we consider an improved data model, and propose a low-complexity algorithm for sensor gain-phase errors estimation using an auxiliary source with known direction. The proposed algorithm has good performance in low signal-to-noise ratio (SNR). Moreover, it performs independently of phase errors. Computer simulations are presented to show the efficacy and performance of the proposed algorithm.
