摘要： A process is described to detect conducting objects buried in the ground by sending a series of electromagnetic pulses and the return signal. The signal characteristics stored in the database are sets of numerical data which each define characteristics of decreasing curves of the values of previously-received signals then, in a search phase, the numerical values of samples ranked 1, 2, . . . n are recorded, representing a real decreasing curve of a received signal. The average real decreasing curve is created by determination of the average value of the samples, each of which represents the average value of the values of the samples of the same rank. A value representing the difference between the set of characteristics of the real average decreasing curve and each of the sets with the same database characteristics is calculated. The smallest of the differences is compared with the threshold value. There is detection if at least one difference is less than the predetermined threshold, the object and its burying depth being defined as the object in the database which had the minimum difference value.

摘要： A procedure for locating a mobile magnetic target (2) using magnetic measurements includes determining first and second positions (P1 and P2), and a first possible speed (V) of the target (2) along a first direction (Y), determining a third position on a trajectory (28) defined relative to the first direction as a function of the first possible speed (V) and of a later moment in time, and determining the approach position of the target and its speed as a function of the first, second and third positions.
