The Georgia Tech Research Institute (GTRI) operates an indoor compact range used for radar cross section measurements and antenna testing. The facility is shielded against electromagnetic interference and used for both internal research and collaborations with industry. The range is 18 feet high, 24 feet wide, and 60 feet long. It can test at frequencies ranging from two gigahertz to 100 gigahertz, and that range can be extended down to 200 megahertz to accommodate UHF antenna testing. Shown under test is a Skywalker X8 airframe that is being used as a test bed for swarming UAV research. The aircraft is undergoing antenna pattern characterization as part of an investigation into inter-aircraft communications. Photo by Rob Felt.
