SYSTEM FOR PASSIVE LOCATION OF A MOBILE SUBMARINE OBJECT

摘要

The invention relates to systems for the location of a passive torpedo is launched against a surface ship or a - marin.elle consists of releasing a buoy (401) of which the vessel moves rapidly. This buoy is provided with a hydrophone and transmits the acoustic signals received by that - at the building by radio or cable. The location of the torpedo is carried out on the basis of the delay between the acoustic signals received by the buoy and the building by determining the point of intersection between the hyperbola isoretard and the right of the azimuth angle of the target is given by the passive sonar carried by the bâtiment.elle in particular makes it possible to improve the fight against the torpedoes by small bases.
