DEVICE FOR DETECTING HYDROACOUSTIC NOISE SIGNALS BASED ON QUADRATURE RECEIVER Russian patent published in 2015 - IPC G01S15/04 

Abstract RU 2549207 C2

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.
