Synthetic Aperture Radar (SAR) Remote Sensing Fundamentals

Earth observation is no longer limited by daylight or cloud cover. Synthetic Aperture Radar (SAR) allows us to map the planet in any weather condition, making it an essential tool for modern remote sensing. This text-based course guides you from the absolute basics to confidently understanding how radar signals interact with the Earth's surface and how to interpret SAR data. What you'll learn: - Understand the physics of active microwave remote sensing and how SAR differs from optical imaging. - Analyze SAR geometry, including look angles, polarization, and common distortions like layover and shadow. - Explore SAR Interferometry (InSAR) principles to measure surface deformation and topography. - Interpret Polarimetric SAR (PolSAR) to distinguish different land cover types and surface roughness. - Learn how modern cloud-optimized data formats and open-source tools are used to process radar imagery. You will start with the fundamental physics of radar backscatter and signal propagation before moving into complex applications like interferometry and polarimetry. Through clear, written explanations and conceptual data walkthroughs, you will build a strong intuitive grasp of radar remote sensing. This course is designed for beginners in GIS, environmental science, or remote sensing, and requires no prior experience with radar data.
