Abstract :
In this paper, a new direction-of-arrival (DOA) estimation technique for partly calibrated arrays with pairwise calibrated sensors is proposed. Our approach is shown to substantially outperform several popular DOA estimation methods applicable to such partly calibrated arrays. As a byproduct, our algorithm can also blindly estimate the source spatial signatures.
