<p>According to the method signals adapted to the medium and to the kind of discontinuity to be analyzed are transmitted towards the discontinuity (D) from a number of transmitting point (l<Sub>1</Sub>) located on at least one base line (L,), these signals are received at a number of reception points (1<Sub>2</Sub>) located on at least one base line (L<Sub>2</Sub>) placed on the opposite side of the discontinuity (D) as far as the transmission paths are concerned; the received signals are then analyzed to obtain the position and shape of the discontinuity. In certain cases the echos and backscatter are also analyzed.</p><p>At least one of the base lines (F<Sub>1</Sub>) carrying the transmission points (I<Sub>1</Sub>) does not intersect with at least one of the other base lines (F<Sub>2</Sub>) carrying the reception points (1<Sub>2</Sub>).</p><p>This system and method may be used to determine the position and shape of underground discontinuities, to analyze the internal structure of human or animal bodies, or any other inanimate object in any medium.</p> |
