SAR / InSAR

SAR (Synthetic Aperture Radar) and InSAR (Interferometric SAR) are active microwave remote sensing techniques used for:

  • Deformation mapping
  • Subsidence monitoring
  • Volcanic activity
  • Glacier dynamics
  • Landslides

📡 SAR Sensors

  • Sentinel-1
  • ALOS PALSAR
  • TerraSAR-X
  • RADARSAT
  • RISAT (India)
