A new antenna and radar-cross-section measurements facility consisting off our anechoic chambers has recently been constructed at Lincoln Laboratory on Hanscom Air Force Base. One of the chambers is a large compact range facility that operates over the 400 MHz to 100 GHz band, and consists, in part, of a large temperature-controlled rectangular chamber lined with radar-absorbing material that is arranged to reduce scattering a composite rolled-edge offset-fed parabolic reflector a robotic multi-feed antenna system and a radar instrumentation system. Additionally, the compact range facility includes a gantrycrane system that is used to move large antennas and radar targets onto a positioning system that provides the desired aspect angles for measurements of antenna patterns and radar cross section. This compact range system provides unique test capabilities to support rapid prototyping of antennas and radar targets.
