    Radar Remote Sensing team of Tartu Observatory develops Synthetic Aperture Radar (SAR) applications and does corresponding research. 

    SAR is a remote sensing instrument that is sensitive to objects structure and di-electrical propertires, it is usually installed on a satellite or an aeroplane. Besides its long usage in reconnaissance numerous SAR civilian applications have proven very useful: ice mapping, oil spill detection, soil moisture mapping and digital elevation models (DEM) generation. E.g. The global DEM in Google Earth is generated with interferometric SAR.

    As 2014/2015 we are mainly developing two applications: grassland parameters retrieval and cutting detection with polarimetric and interferometric SAR and forest biomass mapping with interferometric SAR. We have developed methodology for flood mapping in temperate forest. Our proposed solution for urbanisation monitoring won the 2013 „Copernicus Masters“ remote sensing ideas contest DLR Environmental Challenge.

    We cooperate closely with University of Tartu, Estonia and it is possible to do doctoral, master and bachelor thesis work in our team. Besides University of Tartu we have done cooperation projects with AS Regio, Tallinn Technical University Marine Systems Institute, German Aerospace Center (DLR), European Space Agency (ESA), Aalto University, Finland and Norwegian research company Norut.
