Waveguide Invariant Focusing for Broadband Adaptive Beamforming in a Shallow Water Channel

Focusing methods are effective broadband techniques that can reduce the observation time required for adaptive beamforming. However, often focusing methods designed for planewave signals do not prevent broadband covariance matrix rank inflation for shallow-water multipath wavefronts. The waveguide i...
