英文摘要
The study conducted with the theories of remote sensing information in geosciences, hyperspectral and microwave remote sensing mechanism and object’s recognition, remote sensing information transfer in different medium .The separation theory of geometric and physical parameters of the roughness surface and concerned experimental results have been described. Based on an advanced hyperspectral Imager developed in this project and multiband and multipolarizotion radar imageries the imaging mechanism of rocks, vegetation, water etc, object recognition, information extraction and classification have been studied. In this study a wide-band extinction method for aerosol optical thinckness has been developed and applied in the inversion of aerosol optical features in some regions of China.
