WG I/3: SAR and Microwave Sensing

Our Mission

ISPRS Working group I/3 aims to promote the use and the development of SAR processing methodologies, algorithms, and applications. The WG works on the generation and accuracy assessment of 3D or higher dimensional SAR techniques, e.g. radargrammetry, interferometry, tomography, etc. The possibilities provided by SAR big data, especially with the global coverage provided by Sentinel-1A/B, is another important topic.

To this purpose, the WG organizes workshops to exchange the latest developments on SAR data processing and microwave sensing.

Furthermore, the WG organizes international comparative tests on the performance of algorithms for processing SAR data stacks.
