Sentinel-1 consists of two satellites (Sentinel-1A & 1B, with 1C planned) providing C-band SAR imagery for applications like land monitoring, maritime surveillance, and disaster response. |
Sentinel-1 provides: - Backscatter Coefficient (σ⁰): Reflectivity of surfaces (land, water, ice). - Coherence: Surface change detection (InSAR). - Phase Information: Ground displacement and elevation (InSAR). - Polarization (VV, VH, HH, HV): Surface type differentiation. - Doppler Information: Ocean currents and moving object detection. - Georeferenced Radar Images: SAR images in various acquisition modes. |
