An approach to optimal array pattern synthesis based on spherical harmonics is presented. The array processing problem in the spherical harmonics domain is expressed with a matrix formulation. The beamformer weight vector design problem is written as a multiply constrained problem, so that the resulting beamformer can provide a suitable trade-off among(More)
Design and operation of underwater acoustic communications systems require a capacity to model the acoustic preparation conditions under various environmental conditions. For the frequencies of interest to most applications in connection to ocean sensor networks ray tracing technique is normally the preferred method. In this study we use a newly developed(More)
