Biomass sketch

Biomass carries the first P-band synthetic aperture radar in space. It operates in left side-looking geometry with full polarimetric and interferometric capabilities. To penetrate the forest canopy, a large wavelength is necessary (around 70 cm) and means a large antenna of more than 10 m across. The instrument therefore comprises a large deployable reflector with a 12 m diameter projected aperture with an offset feed array and a single-beam.
