Paper Abstract

The results of a series of microwave measurements were made to confirm the relationship between measured brightness temperatures (Tb) and the Fresnel equations as a function of local incidence angle, polarization and frequency. The Phillips Laboratory's microwave transmission code RADTRAN allows the input of surface emissivity or reflectivity and the thermometric temperature of the surface to account for surface radiation properties. The experimental verification was carried out using the Millimeter Wave Analysis of Passive Signatures (MAPS) system. MAPS consists of a spectral camera mounted on an scissors lift tower with elevation/azimuth positioning and operating at frequencies of 35, 60 and 95 GHz, with both vertical and horizontal polarization.
