Abstract
A phased-array antenna system includes an array of antenna feed elements that produces a radiation pattern to provide spot beams within which to receive a signal in a frequency band and carrying communication from a terminal at a known geographic location. A beamformer forms the spot beams; and a channelizer divides the frequency band into frequency subbands, and measures power levels of the signal over respective frequency subbands. And an antenna controller selects a frequency subband based on the measured power levels indicating that the signal includes an identifiable interference, and calculates a set of beam weights based on the measured power level over the selected frequency subband, and based on the known geographic location of the terminal. The beamformer, then, forms the spot beams based on the calculated set of beam weights to thereby suppress at least some of the identifiable interference from the signal.
