"Calibration Apparatus And Method"
Abstract: There is provided an apparatus for calibrating a multi-beam satellite system comprising a beam forming network providing a plurality of signal paths, the apparatus comprising a calibration processor tor determining the phase and amplitude shift of a lest path of the phurality of signal paths by correlating a calibration tone extracted from the test path with a reference cali¬bration signal, the calibration processor being configured to determine the phase and amphtude shifts of the test path for at least two calibration tones of at least two different frequencies. The apparatus also comprises means for applymg a correction based on the determined phase and amplitude shift to the test path in the beam fonning network. The two calibration tones of at least two different frequencies may be calibration tones injected at two different frequencies but also calibration tones translated into two different frequencies by the beam forming network. The invention allows a phase and amphtude shift for any path through the beam forming network to be calculated for any frequency in an operational frequency range of the multi-beam satellite system and corrections to be applied to form or interpret the required downlink or uplink beams of the multi-beam satellite system.
