FIELD: radar ranging.
SUBSTANCE: universal radio-beam device for alarm signalling with low power consumption, comprising a transmitter and a receiver of directed radio-frequency radiation placed on transmitting and receiving sides opposite the guard boundary, forming a detection zone along the security boundary; said transmitter on the guard boundary transmitting side comprises a first signal processor, first output of which is connected to the input of the clock pulse transmitter, the second output of the signal processor through the power amplifier and the microwave generator is connected to the input of the transmitting microwave antenna, and a radio modem with a transceiving antenna is introduced into the receiver at the receiving side of the security boundary, input / output of which is connected to input / output of second signal processor, and first and second signal processors are configured to operate in low power consumption mode.
EFFECT: reduced power consumption.
