SARkit is a suite of Synthetic Aperture Radar (SAR)-related tools in Python developed and maintained by Valkyrie Systems Corporation to encourage the use of National Geospatial-Intelligence Agency (NGA) SAR data standards. With SARkit, you can: - read and write SAR standards files (CRSD, CPHD, SICD, SIDD) - interact with SAR XML metadata using more convenient Python objects - check SAR data/metadata files for inconsistencies This project was developed as the modern successor to SarPy.
