Design of underwater acoustic sensing and communication systems is a very challenging task due to several channel effects like multipath propagation and Doppler spread. In order to cope with these effects, beamforming techniques have been applied to the design of such systems. The broadband nature of acoustic systems motivates the use of beamformers with frequency-invariant beampattern. Moreover, in some cases, these systems are limited by their physical dimensions. Differential microphone… CONTINUE READING
