COMPLEX OF TECHNICAL MEANS OF ANTI-TORPEDO PROTECTION OF A SUBMARINE Russian patent published in 2022 - IPC B63G9/02 B63G8/34 

FIELD: submarines anti-torpedo protection.

SUBSTANCE: invention relates to means of anti-torpedo protection of submarines, in particular to devices for sonar counteracting enemy actions. A complex of technical means for anti-torpedo protection of a submarine is proposed, characterized by the presence of a group of self-propelled autonomous underwater vehicles, each of which is equipped with communication and mutual positioning systems, as well as receiving and emitting hydrophones with the possibility of each vehicle emitting part of the primary and secondary acoustic fields of the submarine in places corresponding to base points of the acoustic field, to form an imitation spatial copy of the acoustic field of the submarine, wherein at least one underwater vehicle in the group is configured to counter move to destroy upon detection of a probing pulse from the attacking torpedo's sonar.

EFFECT: increasing the reliability of the submarine simulation, the efficiency and reliability of the anti-torpedo protection complex and hydroacoustic countermeasures against torpedo attacks.
