Abstract
A system and method to normalize a tracking control signal in a directional antenna system to reduce interference from an interfering adjacent transponder is presented. The system and method scans for the tracking signal along a scan path to produce a received signal strength indicator (RSSI) signal, coherently detects an RSSI image from the RSSI signal, and performs a morphologic feature estimation of the RSSI signal image to produce and output a normalized tracking correction.
