Phase™ SAR Interferometric Processor
Vexcel's Sar interferometric processor, Phase™, is a standalone software system capable of forming digital elevation models and differential centimeter-level displacement maps from spaceborne SAR satellites including ERS, JERS, Radarsat, Envisat and PALSAR. Phase tools can be controlled from a Java-based Graphical User Interface, which allows the user to operate the system both interactively or as a batch processor. The GUI leads the user through the following processing steps:
- Estimation of baseline
- Registration and resampling of SLC
- Creation of interferogram
- Creation of DEM mosaics
- Simulation of interferogram from external DEM
- Registration of simulated interferogram
- Flattening with simulated phase
- Filtering of flattened interferogram
- Refinement of baseline
- Creation of orthorectified displacement map or DEM products
