ABSTRACT:
An echographic technique based method for prospecting of the subsoil or sea bottom and the like, by means of acoustic waves and carried out by the use of an apparatus constitued, in combination of a known acoustic wave transmitting equipment (1) comprising of a body (6, 8) in the inside of which a chamber (9) is formed defined by an internal reflecting surface (7) shaped like a round paraboloid of axis (Y--Y), closed at the base by an elastic diaphragm (5) and filled with a proper liquid, into which acoustic waves are emitted produced by a pair of main electrodes (10a, 10b) associated with an auxiliary discharge priming electrode (11) put between the first ones. The equipment (1) will be installed at a predetermined distance "D" from a receiving equipment (2) having a body structure (6a, 8) substantially like to that of the equipment (2), but that near the focus of it internal parabolodic reflecting surface (7) has a ceramic piezoelectric detector (13) mounted on the lower end of a hollow rod supported by the head (6a) of said body, by means allowing said detector (13) to be moved into the chamber (9) with respect to the focus within a range of predetermined value in any direction.
