ADAPTIVE ANTENNA SYSTEM FOR PANORAMIC RADIO RECEIVER Russian patent published in 2008 - IPC H01Q21/00 

FIELD: physics, radio.

SUBSTANCE: invention concerns radio technology. Objective is achieved due to possibility to define spatial signal parameters of detected radio electronic means in near zone, so that the total of these parametres defines the means location explicitly. System include n antenna elements, n pre-selectors, n lag lines, n adders, control signal generator, difference measurement unit, auxiliary adaptive processor, guided processor, unit of spatial signal parametres definition in far zone, guide signal generator, first switch. Additionally the system features comparison unit with input connected to second input of guided processor, first 'OR' unit, second switch with its second input connected to second output of guided processor, unit of spatial signal parametres definition in near zone, and second 'OR' unit with second input connected to output of unit of spatial signal parametres definition in far zone and output connected to control signal generator input. Second output of second switch is connected to first input of unit of spatial signal parametres definition in far zone, and second inputs of units of spatial signal parametres definition in far zone and near zone serve as frequency code inputs.

EFFECT: expanded application range and functional capacities of adaptive antenna system for panoramic radio receiver.
