In passive underwater sonar, current attention is on large arrays which can provide the needed array gain and high resolution beamforming. However, full-rank adaptive processing for these arrays requires sufficient sample support which if often difficult to acquire in dynamic shallow water environments. Furthermore, complicated acoustic propagation and uncertainties about the ocean parameters can limit the effectiveness of adaptive techniques. Several researchers have proposed mode-based… CONTINUE READING
