METHOD FOR GUIDANCE OF A TORPEDO GUIDED BY WIRES Russian patent published in 2019 - IPC F41G7/20 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment and can be used in guidance systems of remote guided torpedo weapons. Method of remote control of torpedo includes measurement by means of passive sonar of bearings from carrier to target and to torpedo, determination of distance from carrier to torpedo, calculating the value of bearing change on the target, determining on the predicted moment of time predicted bearing on the target and bearing on the torpedo, distant from the bearing on the target by an angle, providing simultaneous separate direction finding of the target and the torpedo, discrete formation of trajectory of torpedo guidance. Then control commands are generated and transmitted along wire communication line from carrier to torpedo, at the specified moments of torpedo control time additionally determining the effective range of the torpedo homing system and linear displacement of the torpedo from the bearing to the target and depending on their ratio forming the torpedo guidance trajectory. At the end of the telecontrol section, the torpedo is brought out to the line of the predicted bearing on the target and is switched to the independent guidance mode with setting the target search calculated heading.

EFFECT: reduction of linear displacement of torpedo from bearing to target in end of remote control section, id est during transition from telecontrol to self-guidance, and improved capabilities of target capturing by torpedo homing system at large firing range.
