FIELD: communication facilities. ^ SUBSTANCE: invention concerns radio technology and can be applied in design of radio communication, radio navigation, control schemes using broadband signals. Effect is achieved by more complete check by differentiating indicators of useful signal and structural interference. Device of broadband signal search includes line part (1), transformable matched filtre (2), k detectors (31-3k), k power units with threshold (41-4k), k keys (51-5k), k logical NOT elements (61-6k), two logical OR element schemes (7 and 8), key notifying of the decision of signal detection (9), trigger (10), counter (11), clock-pulse oscillator (12), channel switch control unit (13) and timers unit (14). ^ EFFECT: reduced probability of false synchronisation to strong structural interference. ^ 6 dwg |
