Antenna range upgrade project Indoor Doppler Antenna Test Range

Abstract

The Indoor Doppler Antenna Test Range at Robins Air Force Base, Georgia, was constructed in the mid-1970's to provide an automated test and calibration capability for the APN-185 and APN-189 navigational Doppler radar antennas. Over time, the capabilities of the facility were gradually enhanced to enable test/calibration of a variety of antennas used in navigation, terrain following, and fire control systems. In the late 1980's, a project was undertaken to upgrade the facility by replacing obsolete hardware components and by redesigning the system software and rehosting it in Ada. The project, which was completed in the spring of 1993, has resulted in notable improvements in system reliability, maintainability, and performance.<>
