Abstract
An eigenstructure method is presented for direction finding in the presence of sensor gain and phase uncertainties. The method provides estimates of the directions of arrival (DOAs) of all the radiating sources as well as calibration of the sensor gains and phases. The method can be applied to low signal-to-noise ratio (SNR) and be suitable for arrays with arbitrary sensor geometries, including linear arrays. Computer simulations are presented to illustrate the performance of the proposed method
