Procedure and apparatus for passive trajectory determination of underwater objects.

摘要

The subject of the present invention is an apparatus for passive trajectory determination of underwater objects (1), comprising submerged sensors (2) capable of transforming the soundwaves (4) emitted by the said object into electrical signals, and a central computing unit (3) receiving the said signals and capable of processing them. This apparatus comprises at least six sensors (2) arranged in pairs (5), the distance between the sensors constituting them, and the direction of their alignment (AA'), as well as the relative position of the said pairs (5) with respect to one another being known precisely, which sensors (2) have a wide pass band for listening to soundwaves. <IMAGE>
