Abstract
A need exists for a method to do monopulse tracking with a single beam phased array antenna. With a monopulse tracker antenna, the satellite, or moving target, will have a beacon signal that the tracker can acquire. The beacon signal may be a preamble in the transmitted signal from the satellite. The monopulse tracker antennas are scanned over the volume, minimizing the error signal. When the error signal is minimal, the antenna is pointed in the direction of the satellite or moving target. Because the tracker needs to know direction offsets in both azimuth and elevation planes, error signals from both planes are needed. The monopulse tracker antenna maintains a radio frequency link to the beacon signal, causing the antenna to lock in the direction of the satellite when the error signal is minimized to zero.
