A bstract Mini‐ sosie consists in using a vibration‐rammer as seismic source and changing the striking rate by varying the engine speed, resulting in a random impulse transmission. The recording instruments are made up of two seismic traces, two constant gain amplifiers and a two‐channel sosie processor which performs the decoding in real time by using the actual transmission times supplied by a captor located on top of the vibration‐rammer's plate. An idea of the possible penetration is given by the recording of a velocity survey. Other results obtained in seismic reflection and refraction are given.
