USE OF RADIOMETERS IN ATMOSPHERIC ATTENUATION MEASUREMENTS

Measurements from radiometers operating at 20 and 30 GHz were used to predict attenuation along the 14 degrees elevation angle from Blacksbu rg, Virginia, toward the Olympus satellite. Both NOAA Dicke switched r adiometers and Virginia Tech total power radiometers collected data in Blacksburg for two months. The radiometrically predicted attenuation for the total power radiometers agreed well with that of the Dicke swi tched radiometers, indicating that the total power radiometer approach can be used for accurate attenuation prediction.
