Title:
COMPENSATING FOR A NON-IDEAL SURFACE OF A REFLECTOR IN A SATELLITE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/189570
Kind Code:
A3
Abstract:
A method is provided that includes measuring amplitudes and phases of signals reflected off a reflector of a satellite, with the amplitudes and phases forming a first set of measurements. The method includes calculating an element correlation matrix as a function of the first set of measurements. The element correlation matrix represents a radiated feed element pattern off the reflector. And the method includes adjusting a formed beam pattern of a beamformer based on the element correlation matrix to thereby compensate for a non-ideal surface of the reflector.
