Abstract
The present disclosure relates to a compact antenna test range (CATR) system. The CATR system comprises a measurement chamber, at least one feed antenna which is configured to transmit a radio frequency, RF, signal, at least one reflector which is arranged to reflect the RF signal towards a measurement area in the measurement chamber, and at least two preferably metallic calibration surfaces which can be arranged at two or more positions in the measurement area, wherein the calibration surfaces are configured to reflect a respective reflection of the RF signal back to the at least one reflector which is, in turn, configured to reflect the reflections of the RF signal back to the at least one feed antenna. The CATR system further comprises a measurement unit which is configured to receive the respective reflections of the RF signal and to determine and/or visualize a time difference between the reception of the respective reflections of the RF signal.
