| S-band SAR (NISAR) | Being developed | 3-year mission to study solid earth deformation (earthquakes, volcanoes, landslides), changes in ice (glaciers, sea ice) and changes in vegetation biomass | Imaging radar (SAR) | |
| L-Band SAR | Approved | L-band SAR instrument offering full polarimetry, high spatial resolution, high sensitivity, low ambiguity ratios and capability for repeat-pass & single-pass cross-track interferometry to measure surface deformation of vegetated terrain, soil moisture, land cover classification, crop type discrimination and its temporal analysis. Furthermore, it will monitor Polar ice sheets and ice caps, and the sea-ice conditions (i.e. type, drift, deformation, concentration, lead fraction), as well as contribute to the European maritime situational awareness. | Imaging radar (SAR) | |
