Abstract
The recently developed concept of narrowband spatial time-frequency distrib utions (STFD's) is extended to the wideband case. A new STFD-based wideband root-MUSIC estimator is proposed. This technique employs an extended coher ent signal-subspace (CSS) principle involving coherent averaging ol er a pr eselected set of time-frequency points rather than the conventional frequen cy-only averaging procedure.
