PCT No. PCT/FR93/00240 Sec. 371 Date Aug. 29, 1994 Sec. 102(e) Date Aug. 29, 1994 PCT Filed Mar. 10, 1993 PCT Pub. No. WO93/18416 PCT Pub. Date Sep. 16, 1993.The invention relates to a device for locating noise emitters with an antenna comprising passive sensors. In a preferred variant, the antenna consists of N acoustic buoys each comprising a pair of hydrophone dipoles exhibiting a double-eight directivity diagram. Each buoy comprises a compass providing a signal Kn representing the heading relative to magnetic North. The pairs of signals (a1-b1 to aN-bN) are subjected to a rotation by the angle Kn. The signals are next digitized and the number P of noise emitters estimated. The locating of these noise emitters can be performed according to two variants (8, 9).
