DEVICE FOR DETECTING HYDROACOUSTIC NOISE SIGNALS BASED ON QUADRATURE RECEIVER

摘要

FIELD: physics, acoustics.;SUBSTANCE: present invention relates to hydroacoustics and specifically to devices for detecting hydroacoustic noise signals in the form of discrete components on the background of additive noise. The result is achieved due to use of quadrature detection in each frequency channel of a passive broadband system.;EFFECT: high noise-immunity of a detector for detecting hydroacoustic noise signals in form of discrete components.;3 dwg
