Abstract
A satellite system includes directional antenna with a gain pattern response having nulls where interfering adjacent satellite signals would be received. Using an electronically scanned array (ESA), sub-arrays of the ESA sample interfering adjacent satellite signals and then filter the sampled signals from the primary single received by the ESA. Digital signal processing increases the accuracy of the filtering process by analyzing the interfering adjacent satellite signal to determine the angle-of-arrival of the signal.
