Abstract

Using a computer-based simulation method, we consider the noise immunity of an individual combined receiver consisting of sound pressure and vibration velocity receivers, as well as the noise immunity of a plane acoustically transparent array consisting of such receivers, are considered. The computer simulation results verify the earlier developed analytic method of calculating the noise immunity coefficient of hydroacoustic arrays for the multiplicative processing algorithm for processes in their channels. It is shown that if the anisotropy of the noise field acting on the combined receiver and array varies in a very wide range, the maximum noise immunity is ensured not by multiplicative but by additive processing.
