SARPROZ is a very powerful and versatile tool that implements a wide range of Synthetic Aperture Radar (SAR) processing techniques.
Main characteristics of SARPROZ:
- User Friendly Graphical Interface: no other language knowledge is required for standard uses.
- Based on Matlab: advanced users can very easily develop their own software extensions. Data and parameters are very easily imported/exported using Matlab.
- It can be compiled and it runs independently from Matlab on any platform (Unix, PC, Mac).
- Completely parallelized: SARPROZ can run on multiple CPU cores or computer clusters automatically.
Processing options/modules included in SARPROZ:
- 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.
- Change detection exploiting image time series.
- Image classification based on results of previous modules.
Auxiliary features of SARPROZ:
- Results/Data visualization and analysis:
- Histograms generation with any of the data/results processed by the software, for any selection of pixels.
- Plots generation in 2D, 3D, with colors or densities with any of the data/results rocessed by the software, for any selection of pixels.
- Images generation with any of the data/results processed by the software.
- Results/Data exportation in three main forms:
- Geocoded raster images in different formats.
- Geocoded point-information, in 2D or 3D, with detailed information for each point (for GIS or Google Earth).
- Hierarchical kmz files for a very efficient visualization in Google Earth.
- Small area analysis with a threefold purpose:
- Test processing of any of the techniques previously listed to quickly check the best approach (that depends on available data, area to analyze, aim of the estimate).
- Browsing of final results on georeferenced optical layers, with possibility of displaying in colors any processing results and selecting point targets for characteristics listing and time series plotting.
- Training of neophytes’: new users can learn SAR, InSAR, PSI thanks to the full- featured analysis over a small area through a step-by-step processing path.
