Abstract
New calibration methods are presented for bearing estimation with sens or location uncertainties, which are based on eigenvalue decomposition of the sample covariance matrix and three or more nondisjoint sources in known bearings. The methods can be applied to arbitrary arrays, in cluding linear arrays, require fewer computations, and are suitable fo r low signal-to-noise ratio (SNR) cases. Computer simulations are give n to illustrate the performance of the proposed methods.
