The application of multiple signal classification (MUSIC) as a direction-of-arrival (DOA) estimator for the wideband, time varying frequency-hop spread-spectrum (FH/SS) signal environment is described. Both block and adaptive approaches are discussed for a multiple FH emitter environment. Results from simulation studies of the block and adaptive versions of MUSIC, which were performed in order to examine their resolution performance, are presented.>
