FIELD: short-pulse signal radiators for high-resolution equipment. SUBSTANCE: transducer has active element built up of thirteen identical sections arranged in number ascending order from rear strap to front one and braced together by means of stud with nut. Each section has periodic set of piezoceramic rings and flexible annular sphere-plastic shims glued together. Transducer also has Barker signal generator, transformer, and LC circuits. Active element section is electrically connected to transformer secondary winding. EFFECT: improved resolving power; improved design. 3 dwg
