MULTI-STATIC UNDERWATER SURVEILLANCE SYSTEM Russian patent published in 2020 - IPC G01S15/87 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to the field of hydroacoustics, namely to multi-static underwater surveillance systems. Solved technical problem is improvement of composition and structure of MUSS. Said technical result is achieved by the fact that the entire area of the controlled sea region is divided into adjacent identical squares, including one IGS located in the center of the square, and a multiple of four PGS set located inside the square. Amount of PSG and their arrangement are calculated taking into account the following conditions: -at each point of the square the probability of detecting an underwater object in given hydroacoustic conditions should be not less than a given probability of detection at a given probability of false alarm; -squared area should be maximum possible; -number of PGS placed in a square shall be minimum possible.

EFFECT: determination of minimum amount of IGS and PGS and geographic coordinates of their installation to ensure a given probability of detecting an underwater object of a given class at a given probability of false alarm when the object is located in any point of the monitored area.
