Method and device for the production of acoustic and seismic signals

The acoustic/seismic signal generator (1) is designed to deceive mines fitted with acoustic and/or seismic sensors. The device includes at least a drum (2) rotated by motors (5). Attached to the drum is a weight (8) via a fixing (9) which positions the weight (8) at a distance from the drum (2). The...

Beschreibung
Zusammenfassung:	The acoustic/seismic signal generator (1) is designed to deceive mines fitted with acoustic and/or seismic sensors. The device includes at least a drum (2) rotated by motors (5). Attached to the drum is a weight (8) via a fixing (9) which positions the weight (8) at a distance from the drum (2). The weight (8) is designed to strike periodically the ground surface when the drum rotates so as to generate an acoustic and seismic signal equal to the strike period of the weight (8).
