SIGNAL (SAR for Ice, Glacier and oceaN globAL dynamics) is a proposal for an innovative Earth observation mission, under study at German Space Agency. The mission objectives include the determination of ice topography and its temporal changes, the monitoring of fast-flowing glaciers, and the characterisation of ocean currents, by using Ka-band synthetic aperture radar (SAR). Two approaches to the mission, including a single satellite with multiple antennas and two free flyers, are presented and critically discussed. A preliminary performance analysis for the key mission measurements has been performed and will be presented.
