Advanced Remote Sensing

  • Multifrequency/Polarimetric SAR Data Processing and Analysis

    • Multifrequency and Polarimetric SAR data are analyzed principally using multi-band analysis techniques with SAR-specific adaptations. This approach allows separation of materials based on their frequency and polarization signatures, related to physical processes at the 3 - 70 cm scale for X-, C-, L-, and P-band Radar systems.  Adaptive filters and texture analysis are used to further separate morphological units.  Results can be provided in GIS-ready form.

    • Other services offered include synthesis of specific SAR frequency/polarization combinations, image enhancements and customization, image georectification and mosaicking and production of softcopy and hardcopy image maps at specified scales and map projections.

     

    • Examples of data types supported include SIR-C/X-SAR, JPL AIRSAR/TOPSAR, ALOS PALSAR, TerraSAR-X.  Other SAR data types can be accommodated on request.

    Interferometric SAR

    • Interferometric SAR (InSAR) is used to produce high quality digital elevation models from multiple SAR scenes. Data supported include ERS-1&2, ENVISAT, PALSAR, TerraSAR-X, Tandem-X. Data from other SAR systems capable of interferometric measurements can be accommodated on request.

     

    • Differential Interferometric SAR (DInSAR) is used to determine ground displacement related to events such as earthquakes, landslides, subsidence, volcanic activity, and similar occurrences. Data supported include ERS-1&2, ENVISAT, PALSAR, TerraSAR-X, Tandem-X. Data from other SAR systems capable of interferometric measurements can be accommodated on request.
