DEVICE FOR RADIO-TECHNICAL CONTROL OF RADIO RADIATION SOURCES Russian patent published in 2010 - IPC G01S3/46 

FIELD: physics, radio engineering.

SUBSTANCE: invention is related to radio engineering and may be used to detect bearing and frequency of radio signal in systems of radio technical control. Device comprises the following serially connected components: the first receiving antenna, the first amplifier of high frequency, the first power divider, frequency metre and unit of measurement results processing and bearing calculation, serially connected the second receiving antenna, and the second amplifier of high frequency, serially connected the third receiving antenna, the third amplifier of high frequency and the first metre of phase difference, the second inlet of which is connected to the second outlet of power divider, and outlet - to the second inlet of measurement results processing and bearing calculation unit, at the same time focal axes of receiving antennas are parallel and match in direction with direction towards center of bearing sector, the second metre of phase difference, the first inlet of which is connected to outlet of the second UHF, the second one - to the third outlet of power divider, and outlet - to the third inlet of measurement results processing and bearing calculation unit, at the same time unit of measurement results processing and bearing calculation is arranged as three-inlet, and rough value of Θ_r bearing is calculated using the following formula: where λ is length of controlled signal wave; a is distance between focal centres of the first and second receiving antennas; Δφ is difference of phases of controlled signal at the outlet of these antennas.

EFFECT: simplification of stated device and increase of its reliability.
