SAR Calibration Toolbox (SCT)

Sar Calibration Toolbox (SCT) is the official Aresys Python toolbox for SAR quality data processing. This software provides several features to perform a quality analysis of SAR L1-B products (both SLC and GRD).

SCT is an open source tool developed in the framework of EDAP (Earthnet Data Assessment Project) and SAR MPC (Mission Performance Cluster) projects. For more details please visit:

Software Architecture

Here is a brief overview of the software architecture of SCT:

The SCT framework is designed to be analysis-agnostic with respect to input product formats. Product format plugins are used to decouple the analysis code from the input data type, allowing new input product formats to be added without modifying the core analysis code.

Same goes for the product-agnostic quality analyses. Analyses plugins are used to decouple the analysis code from the orchestration and product format I/O, allowing new analyses to be added without modifying the core software.

Supported Missions and Products

This tool is designed to be input product agnostic, and can be used to perform a quality analysis on any SAR L1-A/B product (among those supported) in a standardized way. To check if the mission or product type to be analyzed is currently supported by this tool, please refer to the SCT Product Format Plugins documentation.

Available Quality Analyses

Several analyses to assess quality of SAR L1A/B products have been developed and are available as SCT plugins. They can be installed separately or bundled together with the main software using the [recommended] optional dependency group installation.
