Learn how you can use Synthetic Aperture Radar (SAR) analysis tools in ENVI SARscape® to support your Earth Observation applications. This class will cover background information on SAR data and satellites to tips and tricks for end results, making it useful for both beginners and experienced SAR researchers.

SAR can detect surface phenomenology, penetrate clouds, and deliver observations not possible with optical imagery. The increasing availability of cost-effective SAR data can be beneficial to applications such as:

This 4-day training will guide you through the processing and analysis tools in SARscape starting with setting up the SARscape working environment, to moving through the tools, to generating final products. Applications of SAR data will be addressed using different approaches and techniques such as backscatter coefficient analysis, coherence, interferometric and differential interferometric techniques, and multi-temporal analysis.

The training will involve the use of the freely available Sentinel-1 data as well as high-resolution data (TerraSAR-X and COSMO-SkyMed).
