Abstract

An original eigenstructure-based method for direction finding in presence of sensor gain and phase uncertainties is presented. The method has been developed in order to estimate the directions of arrival of non-circular radiating sources for any geometrical array configuration. The gain and phase of each sensor are also provided by this technique. We show that this method works even in the case where the number of sources is larger than the number of sensors. The proposed procedure gives very good results as we show through two demonstrative computer simulations
