FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used in radio monitoring means. In the recognition device, the fact of rotation of the antenna-feeder system of the radar station is additionally established and complexed with the result of determining the type of modulation, corresponding to the radar station signals, at the output of the N channel maximum selection circuit.
EFFECT: high probability of recognizing a radar station operating in survey mode.
