Abstract

This paper describes trade-offs between the science requirements, basic operational parameters, and expected sensor performance for selected satellite radiometer concepts. The preliminary designs of real aperture systems utilizing novel lightweight compact-packaging techniques are used as a means of demonstrating this technology. Radiometer subsystem design and calibration as well as antenna and feed design criteria and techniques required are also presented. Preliminary results show that novel designs and packaging techniques compatible with small launch systems coupled with state-of-the-art radiometer designs hold promise for high-resolution Earth science measurement systems
