SYSTEM OF SOUND SOURCE Russian patent published in 2003 - IPC

FIELD: seismic survey. SUBSTANCE: proposed system includes flexible structural modules joined together to form extended flexible structure with essentially constant form in cross-section over outer diameter and size. Extended flexible structure can be stored on drum unit and can be unreeled from drum unit in process of prospecting and reel up drum unit without separation of modules. At least one module incorporates device forming pulse sound. EFFECT: simplified design of system, reduced time of unreeling and reeling of system, preservation of serviceability in water basins with floating ice fragments and intensive vegetation. 9 cl, 11 dwg
