FIELD: radio engineering, communication.
SUBSTANCE: device includes a blanking unit of pulse interference (1), N band-pass filters (8.1-8.N), two adders (9, 16), analogue-to-digital converter (10), two memory units (12, 15), delay unit (18), two multiplier units (13, 19), fast Fourier transformation unit (14), inverse value calculation unit (17), narrow-band interference blanking unit (20); correlation device (21), reference signal shaping unit (22), threshold unit (23) and amplification adjustment unit (2) including controlled attenuator (3), amplitude detector (4), two comparators (5, 6), counter (7) and delay unit (11).
EFFECT: reducing probable non-reception of a signal under conditions of action on a radio receiving device of blanking interference with a dynamically changing level.
