The Dual 37GHz/94GHz Radiometer.

摘要

The report contains a description of the design and development of a dual-frequency radiometer. Particular emphasis is placed on its versatility and the calibration technique used. A reference antenna with a spatially offset beam provides a reference for background discrimination if a tracking mode of operation is desired. Radiometer sensitivity at an integration time of one second is 4.4K at 37GHz and 8.2K at 94GHz. (Author)
