sarpyx is a specialized Python package for advanced Synthetic Aperture Radar (SAR) data processing, sub-aperture decomposition and full integration with ESA's SNAP (Sentinel Application Platform) engine. It is tailored for researchers and developers.

Key Features

• 🛰️ Sub-Aperture Decomposition
  Perform azimuthal sub-band partitioning for enhanced resolution, motion sensitivity, and squint-angle diversity exploitation.

• ⚙️ SNAP Engine Integration
  Interface directly with the SNAP Graph Processing Tool (GPT) to automate calibration, coregistration, interferometry, and other Level-1/2 workflows.

• 🗂️ Modular Processing Pipeline
  Chain together preprocessing, sub-aperture slicing, interferogram generation, and differential phase analysis with customizable steps.

• 📦 Data Compatibility

  • Native support for Sentinel-1 SLC (SAFE format)
  • Efficient in-memory SAR matrix manipulation via xarray and numpy
  • Output geocoded products for GIS integration

• 🔌 Extensible Architecture
  Designed for interoperability with geospatial libraries like rasterio, geopandas, and pyproj.
