INTELLIGENT RADIORAY ALARM SENSOR Russian patent published in 2017 - IPC G08B13/00 

FIELD: physics.

SUBSTANCE: sensor contains a transmitter and a receiver of the directional radio emission placed at the opposite sides of the transmitting and receiving protective boundaries. The transmitter includes a power amplifier, a microwave generator, a microwave transmitting antenna, the first signal processor, the first temperature sensor, the first thermostat, and a clock transmitter. The receiver consists of a receiving microwave antenna, a microwave amplitude detector, a low frequency amplifier, a filter, the second signal processor, a clock receiver, the second temperature sensor, the second thermostat, and an actuator. Each of the microwave antennas generates narrow beam patterns oriented in space toward each other. The first signal processor is adapted to control the radiation frequency stability with temperature. The first and the second signal processors are adapted to provide the sensor performance in the extreme temperatures (-70…60)°C. The second signal processor is adapted to provide the interference-free clocking on the radio beam and the wireline, and also to use the intelligent algorithm of the signal processing based on the movement speed of the intruder in the detection area and the time analysis of his arival in each of the Fresnel zones.

EFFECT: use of the intelligent software features of the sensor work in the difficult climatic conditions in the presence of the high levels of natural and man-made interference.
