FIELD: radio engineering; radio navigation; radio navigation; radio control. SUBSTANCE: device has input band-pass filter, series-connected delay element and first subtracter, as well as second subtracter, input of which is connected to output of input band-pass filter, and link with nonlinear amplitude characteristic containing third subtracter, output of which serves as entire device output and is connected to second subtracter output. Its output is connected to first subtracter input. Device also includes nonlinear converter, input of which is connected to second subtracter output, and output is connected to third subtracter input. Second subtracter has N auxiliary compensation inputs, each of them being connected to output of controlled phase corrector of respective unit which forms n-narrow-band interference compensation signal. Every unit consists of two narrow-band filters, retunable generator with units of phase automatic frequency control and automatic control of transmission ratio, unit controlled by signal from narrow-band filter output and switching the compensating signal coming to input of unit controlled phase corrector during action of narrow-band interference, frequency detector, and controlled phase corrector. Input of first narrow-band filter is connected to first subtracter output, and input of second narrow-band filter is connected to second subtracter output. EFFECT: enhanced interference suppression. 1 dwg
