X-band narrow-beam radiometer for DSS 13
Abstract
The design and testing of a narrow-beam X-band (8.44 GHz) radiometer is described. Continuous calibration is obtained by switching the receiver sequentially among the hot termination, ambient termination, and antenna noise positions. The measured antenna noise temperatures (10 second total integration time) have a standard deviation of about 0.4 K, which is in good agreement with theory. It is felt that radiometer performance is satisfactory for the purpose of making atmospheric noise temperature measurements.
