An algorithm for a combined acoustic signal receiver

It is proposed sorting the instantaneous values of oscillatory velocity and acoustic pressure using the criterion of the similarity with signals in a plane wave using a combined acoustic-signal receiver. Part of the received instantaneous values are rejected, the Poynting vectors are calculated and their angular selection is carried out. Modeling showed that the algorithm enables two sources, separated by 2° in all, to be resolved even if their mean levels differ by 6 dB.
