ABSTRACT:
A system and method for selecting and combining satellite communication signals from multiple antennas. The system includes at least two signal paths, each coupled to a separate antenna, and a combiner for combining signals from the two paths for processing by a signal processor. At least one of the two paths includes a signal delay unit. The signal processor can distinguish a signal received from a source on one of the antennas from that signal received from the source on the other antenna based on a signal delay produced by the signal delay unit. Each signal path includes a variable attenuator for selectively coupling each signal path to the signal processor. The signal processor determines the quality of the signals received along the signal paths, and provides data regarding signal quality to a control processor, which manipulates the attenuators to couple the signal path having the highest quality signal to the signal processor.
