Zusammenfassung:The present invention relates to antennas for radio frequency telemetry applications, and more particularly to a system and method for directing an adaptive antenna array in the direction of an aircraft in flight in order to establish a radio frequency (RF) communication link between the aircraft in flight and a receiver. A system for directing a receiving lobe of an adaptive antenna array toward an aircraft in flight includes an aircraft position vector calculator and an antenna weight vector generator. The aircraft position vector calculator receives aircraft position information from an aircraft tracking service and calculates, based upon the aircraft position information it receives, an aircraft position vector g. An antenna weight vector generator receives the aircraft position vector g from the aircraft position vector calculator and generates, based upon the aircraft position vector g, an antenna element weight vector w. The antenna weight vector w is applied to the elements of an adaptive antenna array to direct a receiving lobe of the array towards an aircraft in flight.
