Abstract: Abstract Nowadays phased microphone arrays have become a standard technique for acoustic source mapping. Compared with the conventional delay-and-sum beamforming method, deconvolution approaches such as DAMAS successfully improve the spatial resolution, however require high computational… read more here.
