Example of Atmospheric Phase Screen Processing Module
- Synthetic Aperture Radar (SAR) image processing: SLC coregistration, SLC equalization and calibration, Reflectivity Map calculation, extraction of pointwise targets.
- SAR Interferometry (InSAR): orbital data processing, interferogram calculation, interferogram flattening, interferogram filtering, phase unwrapping.
- Differential SAR Interferometry (DInSAR): DEM conversion and resampling, topographic phase removal, residual phase processing, motion estimation.
- Stacking of Differential Interferograms (SDInSAR): processing of series of interferograms for atmospheric delay suppression and motion estimation.
- Persistent Scatterers InSAR (PSI): full-processing chain for ground average deformation trend, ground elevation and atmospheric delay estimation.
- Urban Advanced PSI: PS real targets identification and classification (roofs, poles, dihedrals, trihedrals, fences, floor gratings, …).
- Temporary PSI: estimation of temporary targets (new constructions, demolitions, short-time structures)
- Multiple scattering centers PSI: estimation of double or multiple scattering centers per resolution cell in urban sites.
- Non-Linear PSI: estimation of non-linear trends (seasonal polynomial and non-parametric) in target displacement.
- Quasi-PSI: an advanced technique to estimate ground average deformation and ground elevation in areas where no PS targets can be detected.
- Unwrapped-PSI: time series analysis of unwrapped interferograms.
- Multi-Sensor analysis: combination (coherent or un-coherent) of data acquired by different sensors, with different characteristics (frequency, polarization, …) under different geometries
- DEM processing based on InSAR/Multi-Temporal InSAR results for DTM and/or DSM extraction
- Change detection exploiting pairs of images.
- Time Series Change detection exploiting image time series.
- Image classification based on results of previous modules (partly under development).
