RADIO METHOD OF EXTRACTING INFORMATION Russian patent published in 2013 - IPC H04W64/00 

FIELD: radio engineering, communication.

SUBSTANCE: distance dn between antenna phase centres of two groups of radio objects, including mobile objects, is measured, and spatial coordinates of the object are measured using the dn and introduced parameters in accordance with disclosed simple measurement equations. The method enables automatic measurement of coordinates at a high speed for a large number of objects and can be implemented by modern hardware components and microprocessor technology.

EFFECT: high efficiency and simplification of corresponding radio systems.
