We develop and provide the Sigma-SAR<\/strong> software, which processes time-series SAR imagery acquired by Earth observation satellites with high geometric and radiometric accuracy.
The software enables advanced analyses such as ground subsidence and uplift, deforestation, disaster monitoring, land-use change, and change detection.<\/p>\n\n\n\n

In addition, we offer contract-based analytical services that quantitatively and accurately extract environmental changes using these datasets.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Sigma-SAR overview
Consists of four types of execution modules.<\/h3>\n\n\n\n

1) SARimg.exe<\/strong> \u2013 Performs SAR imaging, map projection, polarimetric analysis, and related functions.
2)INSAR.exe<\/strong> \u2013 Executes interferometric SAR (InSAR) processing.
3) MOSAIC.exe<\/strong> \u2013 Handles SAR image mosaicking.
4) ASM.exe (Advanced SAR Module)<\/strong> \u2013 Supports the ingestion of various SAR datasets and enables highly accurate time-series analysis. It is designed to be used in combination with 1) and 2).
5) Operating System<\/strong> \u2013 Linux
6) Deployment Options<\/strong> \u2013 On-premise, AWS, and Tellus<\/em> (planned for December 2025)
