FIELD: radio engineering.
SUBSTANCE: invention relates to pulsed information receivers and is intended for use in electronic intelligence stations and passive target designator systems as equipment determining the type of chirp modulation of composite signals. Device includes an auto-correlator, first threshold unit, key, "interval-code" converter, first register, divider, second threshold unit, coincidence unit, envelope detector, comparator, uni-vibrator, second register, delay element, element I and pulse counter, connected accordingly.
EFFECT: technical result is device efficiency increase by high-reliability recognition of signals with chirp phase manipulation.
