Lars Ulander
Professor at
Chalmers, Space, Earth and Environment, Microwave and Optical Remote Sensing
Lars Ulander is professor in radar remote sensing as well as research director at the Swedish Defence Research Agency (FOI). His research is focused on radar systems, in particular signal and data processing for synthetic aperture radar (SAR) in different applications. His research has resulted in new radar systems and new knowledge about SAR and ground imaging in the VHF and UHF bands. He is one of the proposers for the BIOMASS satellite mission which is under development by the European Space Agency (ESA). The objective of BIOMASS is to produces yearly global maps of forest biomass. It will be the first SAR satellite operating in the UHF-band (432-438 MHz) and launch is scheduled 2020.
