Fast algorithm for gain and phase error calibration of linear equi-spaced (LES) array
Y.H. Sng, Youming Li · 2002
The problem of determining the direction-of-arrival (DOA) of multiple sources impinging upon a LES array in the presence of sensor gain and phase errors is addressed. We propose a simple and fast calibration algorithm that does not require any a priori knowledge of the DOA of a signal. Numerical examples are provided to demonstrate the effectiveness of the proposed algorithm.
