摘要: A new water-vapor radiometer is being developed to determine atmospheric path-delay corrections for geodynamics applications. The has microwave channels at 20.7, 22.2, and 31.4 GHz, includes features which should promote radiometric precision while the same time reduce instrument complexity. will be compact, portable, possess a self-diagnostic capability ensure reliability. performance objective determination of line-of-sight path delay though atmosphere due water vapor with one-sigma error less than 0.5 cm zenith.
