InSAR Techniques

Satellite Interferometric Synthetic Aperture Radar (InSAR) involves the processing of multiple satellite radar data acquired across the same location of the Earth’s surface at different times to map ground and structure motion.

Fugro NPA utilise a collection of satellite InSAR techniques to extract the maximum amount of information on ground and structure motion from all available satellite radar data sources.

  • Differential InSAR

    Differential InSAR (DifSAR)

     DifSAR maps relative surface motion to centimetric levels of accuracy.
  • Persisitant Scatterer InSAR

    Persistant Scatterer InSAR (PSI)

     PSI is an advanced differential interferometric technique capable of mapping ground and structure motion to millimetric levels of accuracy.
  • Corner Reflector InSAR

    Corner Reflector InSAR (CRInSAR)

     CRInSAR involves the monitoring of networks of artificial radar reflectors, for example Corner Reflectors (CRs), deployed across regions, features or structures lacking natural radar scatterers.
