Synthetic Aperture Radar: Foundations

أبرز محتويات الدورة

Remote sensing observations from airborne and spaceborne platforms have become an essential tool in earth observation. They provide an immediate and large-area overview of the evolving earth environment, revealing important information on the state of ecosystems, unfolding natural hazards, as well as geodynamic phenomena at volcanoes, earthquakes, and the cryosphere.

This course will introduce you to Synthetic Aperture Radar (SAR), a remote sensing technology that can see the ground even during darkness and through rain, clouds, or smoke. As a participant in this course, you will gain an intuitive understanding of the information contained in SAR observations. You will learn about the concepts and applications of interferometric SAR and experience how SAR data acquired at different polarizations can reveal a wealth of information about the earth environment. Each SAR analysis concept will be illustrated with relevant applications. Specific topics include:

• The mathematical and physical principles of SAR remote sensing
• How to access and visualize SAR data
• Interpretation of SAR images at different wavelengths and polarizations
• Interferometric SAR (InSAR) concepts
• The principles of Polarimetric SAR (PolSAR)
• A summary of applications of InSAR and PolSAR in geoscience, hazard mapping, and ecosystem monitoring

Learners on the verified track will put their learned knowledge into action in data analysis and data processing exercises, in which class participants will analyze SAR data sets, generate and interpret interferometric SAR data, and explore the importance of polarization in earth observation. Learners who select the verified track will also have access to online computational labs using Jupyter notebooks that will allow deeper exploration and practice.
