Large compensated compact ranges are designed for antenna and payload testing of spacecraft antennas and payload units. The Compensated Compact Range concept (CCR) of Airbus does have two major advantages for such measurements. First of all a small cross-polarization (< −40 dB) for frequencies ≥ 3 GHz due to the compensating reflector design. In addition they provide a scanning capability of the...
The Compensated Compact Ranges (CCRs) of Airbus Defence & Space form a dual-reflector arrangement to create a cross-polar-compensated electromagnetic field in an indoor facility which shows far-field characteristics in close proximity to the reflectors. Serrations are mounted on the reflectors to mitigate diffraction of the waves. The serrations of the main reflector which face the illuminating...
The Compensated Compact Range (CCR) 75/60 of Airbus DS GmbH has been analysed to gain insight into its scattering behaviour. To achieve this aim, an approach based on the plane wave spectrum representation combined with inverse scattering and imaging techniques is proposed. The proposed approach firstly computes the plane wave spectrum of the scattered field from the main reflector by using the two...
Future communication satellites equipped with multi spot beam antennas are providing more than 100 adjacent coverages on earth create very high demands for RF measurements during acceptance test campaigns performed prior to the satellite's launch. The antenna's beam isolation and frequency re-use capability require high measurement accuracies for the related test facility and a high time efficiency...
Large dual, doubly curved reflector compact ranges are typically designed for antenna and payload testing of spacecraft antennas and/or transponder units. The applicable frequency bands are therefore at or above the L-Band. In the recent past several customer requests were raised related to UHF frequency operations at a dual reflector compact range. In order to analyze these effects at UHF frequencies,...
