Midi-MAP du jeudi 24 novembre (en anglais) sur TEAMS : General Aspects Of Synthetic Aperture Radar Polarimetry and its Applications, by Pr Avik Bhattacharya

Active microwave remote sensing has demonstrated its importance across several science disciplines and practical applications. The unique capabilities and global coverage provided by spaceborne radar sensors are acquiring critical contributions to understanding and explaining the mechanisms of long-term climate change and its impacts. From the standpoint of spectral management, active sensors designed to measure land surface processes routinely utilize a wide range of frequencies. Diverse types of radar systems have been used to study the land surface. A polarimetric radar sensor measures the extent to which a surface produces backscatter as a function of the electromagnetic wave

polarization. Such polarimetric measurements provide a unique way to characterize the Earth’s surface. This talk will briefly discuss the characteristics of this new technology and its enormous opportunities for the future.
