Paper Abstract

The AN/FPS-85 radar is a large, fixed-position, phased-array radar located at Eglin Air Force Base, Florida. The radar has a peak radiated power of about 32 MW generated by a 72 X 72 matrix of transmitter elements that are individually rated for a maximum peak power output of 10 kW. The current transmitter modules have no automatic phase nulling capability and no remote output power adjustment capability. The result is a randomly varying amplitude pattern across the beam aperture. Southwest Research Institute is currently under contract by the U.S. Air Force to redesign the transmitter units and supply three operational prototypes. Part of the design and performance upgrade will be an automated, remotely controlled power and phase adjustment system which will utilize a centrally located host computer to send phase and amplitude adjustments to the individual transmitters via a digital serial link.
