Abstract :
Helsinki University of Technology (TKK), Laboratory of Space Technology has developed an airborne two dimensional synthetic aperture radiometer for remote sensing purposes. The radiometer - called HUT-2D - measures the ground target using L-band channel reserved for radio astronomy. Main interests are in soil moisture (SM) and sea surface salinity (SSS) monitoring. The instrument is similar with the European Space Agency´s (ESA) SMOS (Soil Moisture and Ocean Salinity) mission MIRAS (Microwave Imaging Radiometer by Aperture Synthesis) instrument. The HUT-2D instrument will be used in SMOS mission calibration and validation activities. Already, the development work of the HUT-2D instrument has given valuable information to the SMOS project. This paper describes the instrument and presents example airborne measurements in Finnish coastal zone.
