Abstract

System and method for locating intercepted sonar transmissions The invention proposes a system for sonar pulse location (100) for a submarine comprising: 5 -two antennas of linear general shape (101, 102) and substantially parallel with each other, arranged on the submarine, the two antennas comprising a detection antenna (101) and a focusing antenna (102), the detection antenna (101) being of small size with respect to the length of the second antenna (102), each antenna comprising a set of sensors (1010, 1020), 10 -at least one interception module (51) for determining the direction of a sonar emission emitted by an emitter and intercepted by the detection antenna (101), and - a focusing module (52) for determining the distance of the emitter by focusing the paths on the basis of the signals provided by the sensors of the focusing antenna 15 (102), in the direction of the emission determined by the detection module (101).
