Abstract
Geophysical prospecting method for the terrestrial environment, which consists of emitting waves produced by at least two emission sources arranged in the same reference plane at different moments in the medium to be explored, to capture the signals on at least one receiving device reflected on at least one reflector, and in registering the instants of emission of the different waves emitted, the signals received on the receiver being then treated to determine the different travel times of the reflected waves, characterized in that the time intervals that they separate two consecutive wave emissions produced each by one of the emission sources, they are less than the round trip time of the longest wave that propagates in the medium to be explored, because each source produces emission waves separated by a time interval at least equal to said travel time of the waves that propagate in the medium, and because the instants of emission defined by the emission program are such that intercorrelating the series of instants of emission from all sources with the series of instants of emission from at least one of said emission sources, all is obtained throughout of the time defined by said round trip time of the longest wave propagating in the medium to be explored, a function whose ratio of the amplitude of the maximum peak to the amplitude of each secondary residue is greater than the ratio of the amplitudes of the received signals at time intervals that correspond to the given time intervals that separate the maximum wave peak from one of the secondary residues.
