Coherent wideband DOA estimation of multiple FM signals using spatial time-frequency distributions
The previously developed concept of narrowband spatial time-frequency distributions (STFDs) is extended to the wideband case. A new STFD-based root-MUSIC estimator is proposed. This estimator exploits a short-window spatial pseudo Wigner-Ville distribution (SPWVD) to enable application of the subspa...
