发明名称 Plural beam reduction of multipath reflections
摘要 A method and system provides for reduced interference from multipath reflections at the earth's surface during a communication between a vehicle traveling above the earth's surface and receivers at plural ground stations located distantly from each other on the earth's surface. Plural antenna elements are carried by the vehicle and oriented in different direction to provide electromagnetic beams at different orientations and different carrier frequencies. This provides wide area coverage while allowing a receiver to be tuned to a signal received from one antenna element while attenuating a multipath reflection at a carrier frequency utilized by another of the receivers.
