Abstract
The feasibility of using spaceborne microwave
radiometry to retrieve geophysical parameters is described. The study
concentrates on the development of inversion techniques for multichannel
spaceborne radiometers, especially the statistical inversion approach.
The applications of the planned MIMR (Multi-Frequency Imaging Microwave
Radiometer) instrument are discussed. The inversion algorithms used are
conventional algorithms for different applications and the statistical
inversion approach. Comparisons between results from different inversion
algorithms are presented. The statistical inversion approach has been
found to give promising parameter retrieval accuracies and has the
potential to improve the operational use of passive spaceborne remote
sensing. An analysis of the sensitivity of the radiometer apparent
temperature to different geophysical parameters and the statistical
behavior of the atmospheric transmissivity are presented.
