Title
A Ka-band Interferometer for Cryospheric Applications-Instrument Description and First Results
Abstract
Characterization of the Earth's ocean topography and cryosphere are among NASA's strategic goals for the next decade. This is because knowledge of the ocean surface topography (and hence thermal energy) and the estimation of snow content, ac- cumulation and snow water equivalent in the polar and mountainous regions provide important input variables which affect global climate studies and the prediction of long term fresh water resources. One method for making relevant measurements for achieving these measurements is through precise topographic mapping using radar interferometry. For this technology, use of mm-wave frequencies (Ku- and Ka-band) is appealing due to the proportional size of the spaceborne structure to the observing wavelength and minimal snow penetration. At high frequencies however, much care in the design of instrument stability and the mechanical deployment structure is needed to achieve accurate measurements. At present, the Microwave Remote Sensing Laboratory at the University of Massachusetts is developing a high performance Ku- and Ka-band interferometer as a prototype for a spaceborne instrument, and is being used in a scaled down ground-based configuration. For the Ka-band version, it will be the first prototype of its kind and would serve as a benchmark for future development.
