Abstract :
For the investigation of microwave propagation on 20 GHz satellite communication links, especially attenuation and depolarization by rain, a new measuring station was built at DLR Oberpfaffenhofen. The station consists of a 20 GHz beacon receiver, a polarimetric 20 GHz Dicke-radiometer, a coherent polarimetric C-band weather radar, and several meteorological instruments. This station is described, and results on differential sky temperature vs. absolute sky temperature, quasi-horizontal propagation, and copolar horizontal attenuation are presented.<>
