FIELD: radio engineering, communication.
SUBSTANCE: in the proposed device, containing the microwave generator and connected with it the transmitter-receiveing antenna, the microwave generator is configured to electrically control the frequency and the autodyne signal selection unit is connected in series to it, the amplifier, the request signal detector and the response pause impulse generator. At that the response pause impulse generator output is connected to microwave generator. The request signal detector consists of the series-connected bandpass filter, the linear detector, the comparator, and the temporary selector for the requested impulses.
EFFECT: increase of the device sensitivity in the requested radio impulse receiving mode, reduction of the time position fluctuations, the depth and duration of the response pause, narrowing of the transmitter-receiver radiation spectrum, increase of its jamming protection from active interference and simplification of the device setting.
