The CATR, which produces far field conditions in a limited indoor space, enables users to characterise antennas that would normally need hundreds of meters of space in an equivalent outdoor range to properly measure. The facility is used to measure antenna characteristics, such as beam width, gain, sidelobe levels and polarisation of various size antennas or antenna subsystems over a frequency range from 750 MHz to 40 GHz. The range can also be reconfigured to measure the Radar Cross Section (RCS) of antennas or other targets. The focus of the Centre for Electromagnetism (CEM) in the Department of Electrical
