FIELD: underwater acoustics, ultrasonic flaw detection, medicine, fish location. SUBSTANCE: parametric acoustic locator is related to location systems designed to detect objects positioned in various media and to classify these objects according to their acoustic resistance. Parametric acoustic locator has generator 1 of high-frequency signals, two frequency dividers 2, 3, two pulse modulators 4, 5, pulse generator 6, two power amplifiers 7, 8, two commutators 9, 10, double-frequency converter 11, receiving converter 12, three selective amplifiers 13, 15, 16, indicator 14, two frequency multipliers 17, 18 and phase detector 19. EFFECT: expanded operational capabilities of acoustic locator. 3 dwg
