Calibration of 20 and 30 GHz radiometers by using the ATS-6 satellite beacons
Abstract
The 20- and 30-GHz transmissions from the ATS-6 satellite were used to calibrate radiometers operating at these frequencies. The slant-path attenuation predicted from radiometric measurements shows good agreement with that measured directly, for values up to 9 dB at 20 GHz (maximum recorded) and up to at least 13 dB at 30 GHz within uncertainty limits of plus or minus 1.0 dB.
