Abstract
A subaqueous underground survey system using a reflection seismic survey method includes: multiple sound sourcesfor generating sound waves in the water; a controllerfor controlling phases of the sound waves; a geophonefor receiving reflected waves of the sound waves; and an observation shipequipped with the sound sources, wherein the controllercontrols phases of the sound sourcesso that the sound waves generated from the respective sound sourceshave a phase difference at a water bottom surface B, thereby controlling generation of shear waves to propagate into the ground.
