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.
