Wideband direction of arrival estimation of multiple chirp signals using spatial time-frequency distributions.
The recently developed concept of narrowband spatial time-frequency distributions (STFD’s) is extended to the wideband case. A new STFD-based wideband root-MUSIC estimator is proposed. This technique employs an extended coherent signalsubspace (CSS) principle involving coherent averaging over a pres...
