Abstract
An interfering radio source present in the primary beam of an array of receiving radio antennas intended to track a spacecraft telemetry signal can cause the array to point off the spacecraft in the direction of the interferer when the incoming signal is used to align the array. By using the narrow spectral shape of the spacecraft signal relative to the (usually) broad shape of the interfering signal, it is possible to separate the two signals and track the spacecraft in the face of this interference. Analysis and simulations are presented to demonstrate how this can be accomplished in a variety of cases.
