We develop signal and image processing algorithms, measurement systems and electromagnetic scattering models. The radar measurements are performed from satellite, aircraft, tower or ground, and cover frequencies from 10 MHz to 100 GHz, i.e. wavelengths from 30 m to 3 mm.

A significant advantage of using radar is the ability to perform observations also during night and poor visibility (clouds, rain, fog etc.), which is particularly important for measurements of the world’s forested areas and in the Arctic. Applications of the research is remote sensing of forests, ocean and sea ice. Examples of projects include measurements of above-ground biomass and water content of forests, ocean currents, sea ice concentration and motion and small-scale ground motion.
