ABSTRACT

The simple method which allows bearing simultaneously in a plane of two incoherent acoustic signals using the combination receiver of oscillatory velocity is considered. The operation of algorithm is studied at the presence of isotropic noise. As a result of processing according to algorithm of model signals it is shown (for example) that for two point sources with identical intensity and 45 grad corner between directions from receiving point, the algorithm does not lose efficiency even if isotropic noise in receiving point is higher by 6 dB than source level. The method allows to change algorithm properties and, hence, to optimize procedure.
