METHOD FOR HYDROACOUSTIC SEARCH FOR AN AUTONOMOUS UNDERWATER BOTTOM OBJECT Russian patent published in 2020 - IPC G01S15/00 

FIELD: underwater navigation.

SUBSTANCE: proposed invention relates to underwater navigation, namely to determination of autonomous bottom underwater object location by means of hydroacoustic navigation system, and can be used in hydroacoustic monitoring systems for various purposes, integrated underwater surveillance systems, positional network-centric systems for hydroacoustic search from underwater search vessel of underwater objects located at the bottom of known marine water area in sleep mode after corresponding mission.

EFFECT: high stealthiness of hydroacoustic search from a surface search vessel of an autonomous bottom underwater object due to using hydroacoustic signals in the search process, masked for possible acoustic background noise of a known search water area – sounds of marine animals, fish, crustacea, sea noise, selection of appropriate structure, amplitude, time and frequency parameters of these hydroacoustic signals, implementation of corresponding actions for emission, reception and processing of hydroacoustic signals on search vessel and autonomous bottom underwater object.
