PANORAMIC RECEIVING SET'S ADAPTIVE ANTENNA SYSTEM Russian patent published in 2007 - IPC G01S5/04 H01Q3/26 H01Q21/00 

FIELD: the invention refers to the field of radio technique particularly to the field of antenna technique and may be used as an organic part of panoramic radio receiving arrangements at controlling radio electronics situation and at estimation of parameters of signals from radio emitting sources.

SUBSTANCE: the adaptive antenna system for a panoramic receiving set has n antenna elements, n delay lines , n adders, in series connected a controlling signal generator, a difference definition unit, an auxiliary adaptive processor and a driven processor whose first output is the output of the adaptive antenna system. At that the controlling signal generator's output is connected to signal inputs of all delay lines, the output of each of them is connected to the first input of the corresponding adder, the output of each of them is connected to the corresponding input of the auxiliary adaptive processor whose correcting output is connected to the second input of the difference definition unit. A new in the adaptive antenna system for a panoramic receiving set is that there are additionally introduced n preselectors, the first input of each of them is connected to the output of the corresponding antenna element, and the output of each preselector is connected to the second input of the corresponding adder and to the corresponding signal inputs of the driven processor, and also there are in series connected a unit of definition of spatial parameters of a signal, whose first input is connected with the second output of the driven processor, a former of guidance signal, and a commutator, whose output is connected to corresponding controlling inputs of the corresponding delay lines. At that the second input of the commutator is the input of the initial mounting of the adaptive antenna system, and the third input of the commutator is the input of switching over of regimes of the work of the adaptive antenna system. At that the second input of the unit of definition of spatial parameters of a signal is the input of a frequency code, and the second inputs of all preselectors are combined and are the input of the preselectors' realignment control.

EFFECT: increases accuracy of estimation of the signal parameters of panoramic receiving sets.
