A new full scale aircraft antenna test facility

A modern outdoor test facility has been designed for comprehensive evaluation of antenna systems on full scale aircraft. The aircraft are mounted to a positioner/tower assembly in an underground handling facility, and are raised to a height of 25 meters by a hydraulically activated lift. A source site 1000 meters downrange provides illumination of a 7 meter radius test zone over a 0.1-18 GHz band. All source site functionality is remotely controlled from the operations center located near the aircraft support tower. The range is designed to provide the capability not only for conventional automated antenna pattern measurements, but also for the support of ECCM testing. This is accomplished by activating both fixed and mobile jamming transmitters available to illuminate the test zone using either CW or modulated waveforms. The FR Model 959 Automated Antenna Measurement Workstation is being enhanced to allow for control of the jammer sites as well as the primary range sites. The system design and operation is described
