Polarimetric Measurements of Natural Surfaces at Millimeter Wavelengths

摘要

In support of the goals the Army Research Office (ARO) and to further scientific understanding, the Microwave Remote Sensing Laboratory at the University of Massachusetts has developed millimeter wave radars capable of measuring polarimetric scattering from natural surfaces including snow cover. These radars, operating at 35, 95, and 225 GHz, have been employed with two goals in mind. The first has been to develop a database of millimeter wave scattering measurements. The second goal was to increase the depth of scientific knowledge pertaining to electromagnetic scattering from terrain at millimeter wavelengths.
