Traceability for microwave remote-sensing radiometry

Abstract
A plan is presented for developing a standard for brightness temperature at microwave frequencies, as well as two different methods for transferring this standard to the microwave remote-sensing community. The standard will be based on existing NIST waveguide and coaxial radiometers, which are calibrated using primary noise standards. The radiometers will be converted (reversibly) to standard remote-sensing radiometers by connecting characterized antennas to the plane at which the device under test is connected in normal use. The underlying theory and plans for implementation are presented. Once developed, the standard and the method for comparison will allow microwave remote-sensing measurements to be traceable to the primary noise standards maintained by NIST.Citation
