Shashi Kumar is working as Scientist in Photogrammetry & Remote Sensing Department of Indian Institute of Remote Sensing (IIRS), ISRO, Dehradun. His research work is focused on SAR Remote Sensing with special emphasis on Polarimetric SAR (PolSAR), Polarimetric SAR Interferometry (PolInSAR) and SAR Tomography for structural and biophysical characterization of forest area. Shashi Kumar has supervised several research works on SAR Remote Sensing and its utilization for forest parameter retrieval. He is also actively involved in NISAR related activities to process the PolSAR & PolInSAR data and its utilization for various applications. He has carried out several research projects on SAR data and some of the major highlights are enumerated below.
• PolSAR and PolInSAR based model development for stem volume and aboveground biomass (AGB) estimation of forest.
• PolSAR Tomography for vertical tree structure of tropical forest.
• Processing of Hybrid-Pol (RISAT-1, FRS-1) and Quad-Pol (RISAT-1, FRS-2) SAR data for semi-empirical modeling for forest AGB estimation.
• Integration of PolSAR, PolInSAR and Terrestrial Laser Scanner (TLS) data for tree height estimation and modelling for forest AGB estimation.
• Polarimetric modeling of Lunar Surface for scattering information retrieval using Chandrayaan-1, Mini-SAR
• Hyperspectral Remote Sensing for Extraction of Aqueous Minerals on Mars and Optical Maturity Estimation of Titanium Dioxide & Ferrous Oxide on Lunar Surface.
