FIELD: radio engineering, possible use in systems for controlling operation of radio-electronic devices with pseudo-random adjustment of working frequency.
SUBSTANCE: in device masking signals arriving from other directions are removed, to detect weak impulse signals with pseudo-random adjustment of working frequency, to prevent splitting effect of contour of impulses due to usage of two decision taking thresholds (first threshold - for detection of frontal impulse front, and second threshold - for detection of back impulse front), and also measurement and recording of values of frequencies and intervals of frequency alternation.
EFFECT: expanded functional capabilities of device for controlling operation of radio stations with pseudo-random adjustment of working frequency, in loaded frequency spectrums with low signal/noise ratio and large number of masking signals.
