METHOD OF SYNCHRONISING EMISSION AND RECEPTION FUNCTIONS IN BISTATIC SONAR Russian patent published in 2014 - IPC G01S15/87 

FIELD: radio engineering, communication.

SUBSTANCE: method of synchronising emission and reception functions in bistatic sonar includes performing operations of emitting and receiving a probing signal, decoding the received information by measuring parameters of the received probing signal, particularly the time of arrival thereof, generating information for locating sea objects based on the result of measuring the time of arrival of the probing signal, and generating information for tuning the sonar receiver by comparing parameter measurement results with contents of a database which stores parameters of possible probing signals. The beneficial effect (see aim of invention given above) is achieved by avoiding transmission and processing of signals bearing mode information, and retrieving said information directly from the received information by probing signal receiving stations.

EFFECT: overcoming prototype shortcomings since with a limited overall emission time, part of the energy of the probing signal can be lost as part of the emission time is spent on mode information, which reduces the sonar range; implementation thereof enables to use as an emitting station only a station which is equipped with means of transmitting mode information, which significantly narrows down the capability for rapid implementation of bistatic sonar based on different hydroacoustic means.
