Abstract :
Descriptions are given of the different systems currently being used in the ETR, and concepts for future upgrades are discussed. ETR is an advanced indoor compact range test facility designed for performing antenna and electromagnetic scattering measurements. ETR utilizes a new dual chamber concept with a blended-edge main reflector and a Gregorian subreflector system, a test chamber design with the absorber type and placement selected for optimum performance, an advanced pulsed/CW radar with a superworkstation for fast and efficient data collection and processing, and a bridge crane for efficient model handling. Isolation from external radio frequency (RF) energy is provided by an RF shielded enclosure. Minor problems that were identified during the preliminary evaluation of the reflector system are discussed
