ROTATING ECCENTRIC WEIGHT APPARATUS AND METHOD FOR GENERATING CODED SHEAR WAVE SIGNALS Abstract of the Disclosure A shear wave generator (10) and a method for its use are provided in which an accurate record of the coded shear wave signal generated is obtained by means of a position sensor (24) having a rotating element (26) and a stationary element (28). This record is used in the correlation of the raw seismic traces obtained. The apparatus includes a rotatable eccentric (14) which is rotated about an axis of rotation (A-A) at varying speeds to generate a frequency-variable coded shear wave signal. In one embodiment of the invention, the apparatus also includes an outrigger shovel (40) through which a sinus- oidal shear wave signal is transmitted into the earth while the rest of the apparatus (10) is caused to alternately decouple from and impact against the earth surface to transmit a coded train of pressure wave impulses into the earth.
