In this paper, a new class of focussing matrices is proposed for use in the Coherent Signal-Subspace Method (CSM) [1]. When the directions-of-arrival of wide band sources fall within more than one group of one beamwidth each, this new class leads to performance substantially better than those suggested in [1] and [4] for directions-of-arrival estimation. New insight into the structures of various focussing matrices and their effect on the performance of CSM is presented. Comparative performance of CSM based on several classes of these matrices is provided based on simulations as well as relative sufficiency analyses.
