The invention relates to a projectile firing device used on a platform and comprising at least two tubes integral with a base. This device is characterized in that the base is mounted able to swivel on a turret around a first, substantially horizontal axis, such swiveling controlled by first drive means, the turret being able itself to pivot with respect to the platform around a second substantially vertical axis and being controlled by second drive means, the horizontal swiveling being made on either side of a median position in which the tubes are oriented with their axes substantially vertical.

Projectile firing device

A system and method for generating acoustic and seismic signals to clear mines equipped with acoustic and/or seismic sensors includes at least one drum driven rotationally by a drive to which drum at least one weight is attached by a fastening device positioning the at least one weight at a distance from drum, the weight being intended to strike the ground periodically as the drum rotates in order to generate an acoustic and seismic signal whose period is the same as that of the striking period of the weight.

Systems and methods for generating acoustic and seismic signals

Mine-clearing coil and device using same

A process and device for detecting objects, in particular mines, dispersed in an area of land. The process implements a plurality of acoustic transducers. After determination of an optimal operational frequency, a brief acoustic pulse is emitted into the ground and then successive temporal reversals of signals received by the transducers focus detection on a first object. At least two transducers for which the propagation times are roughly equal are located and at least one location direction, defined as the mean perpendicular of the segment joining the at least two transducers, is determined.

Exercise mine and programming and simulation device therefor

A process and a device for detecting objects, in particular mines, dispersed in an area of land, or for determining propagation characteristics of an acoustic wave in the ground of an area of land. This process employs a plurality of acoustic transducers and reference targets distributed along borders of the area. After determining an optimal working frequency, a cartography of the propagation characteristics in the ground of the area of land is made, for example, by carrying out several temporal reversals, one after the other, of the signals received by the transducers so as to focus detection on the different reference targets. Objects are detected with the aid of this cartography by focusing detection by temporal reversal on an object and by searching for at least two transducers which have the lowest propagation time for the signal.
