P4004 - Standard for Calibration of Microwave Radiometers in the 300 MHz to 1 THz Frequency Range for Geoscience Applications
Project Details
The scope of this standard is the calibration procedures for microwave radiometers for use in geoscience remote sensing applications. The frequency range addressed encompasses 300 MHz to 1 THz. The standard separately addresses: a) terminology in use in the field of radiometer calibration, such as "absolute uncertainty", "traceable", "inter-calibration", "vicarious calibration" etc.; b) ground, air-borne, and spaceborne radiometers and their respective calibration techniques; c) free-space calibration and single-mode (e.g. guided wave) calibrations; d) calibration of total power, Dicke switched, and differential radiometer architectures; e) calibration of polarized radiometers, including full Stoke's radiometers; f) referencing brightness temperature units to the fundamental unit Kelvin and fundamental constants; Note that the scope includes radiometers for geoscience applications only and will not address radiometer calibration for use in otherre fields such as radio-astronomy, medical, or security.
