In an anti-torpedo device having a towed, noise-radiating jammer (16), to improve the efficiency of the device even against "smart" torpedoes, the jammer (16) is coupled with a hydrophone chain (11) forming the reception antenna of an on-board sonar (15) and an electronic switching system (20) is provided which actuates the noise radiation by the jammer (16) and the signal reception through the hydrophone chain (11) only alternately for predeterminable time intervals. In place of the electronic switching system (20) a controlled filter can be provided which screens out the frequency range of the jammer (16) in the on-board sonar (15). The jammer (16) with transmission antenna (18) may be housed (as shown) within a depth-control buoy (12) at the end of the hydrophone chain (11). |
