ADAPTIVE ANTENNA ARRAY Russian patent published in 2003 - IPC

FIELD: radio engineering; radar, radio navigation, and radio communication systems. SUBSTANCE: adaptive antenna array specially designed for functioning in severe noise environment and for receiving signals under conditions of a priory uncertainty concerning spatial parameters of signal sources (for instance, in radio systems communicating with mobile objects) with respect to noise signals irrespective of their frequency band and power in any signal-noise situation is distinguished from prior art by introduction of Lagrangian coefficient computing unit to replace output power maximizing unit; control input of Lagrangian coefficient computing unit is connected to input device for information about sector of probable directions of signal arrival; first inputs of this unit are connected to respective first outputs of adaptive circuits; first output is connected to fourth inputs of adaptive circuits and second output, to third inputs of adaptive circuits; first outputs of adaptive circuits are connected to respective fifth inputs of adaptive circuits. EFFECT: enhanced noise immunity of antenna array in a priory uncertain situations. 2 cl, 10 dwg
