Basic Investigation on the Feasibility of Multispectral Radiation Information from Microwave Radiometry Measurements for Earth-Scientific Objectives of Remote Sensing

摘要

Multispectral microwave radiometry applied to remote sensing is considered. The data properties were estimated by signal analysis and statistical analysis. The radiant intensity in the 11, 32, and 90 GHz bands is sufficient for a coarse classification of single objects. Detailed investigation requires an extended spectral band 90 GHz. Data reconstruction methods using a priori knowledge result in improved geometrical resolution by increase of the radiometric contrast. Modeling of object specific optical coefficients permits a comparison of scene contents detected under different environmental radiation conditions.
