Radiometer Equation and Analysis of Systematic Errors for the NIST (National Institute of Standards and Technology) Automated Radiometers

摘要

Equations used in the NIST coaxial and waveguide automated radiometers to estimate the noise temperature and associated errors of a single-port noise source are derived in the report. The equations form the foundation upon which the microwave and millimeter wave noise calibration and special test services are performed. Results from the 1-12 GHz coaxial radiometer are presented.
