Abstract
Systems and methods to generate virtual spot beams are provided. The system includes a first antenna that provides a first physical spot beam that represents a radio frequency (RF) signal received from a remote source. The system also includes a second antenna that provides a second physical spot beam that represents the RF signal received from the remote source. The system further includes a beam formation module that is communicatively to the first and second antennas and that performs a beam formation operation on the first and second physical spot beams to generate one or more virtual spot beams.
