Common questions and answers about Synthetic Aperture Radar See also Sentinel-1 FAQ What is radar “aperture?” Unlike the aperture in a camera, which opens to let in light, radar aperture is another term for the antenna on the spacecraft or aircraft. The radar antenna first transmits electromagnetic energy toward Earth and then receives the returning …
Print and video guides to the basics of Synthetic Aperture Radar Printed Material and Websites on the fundamentals of SAR ASF SAR User’s Guide Published in 1993, this is a definitive SAR guide still in use today. Alaska Satellite Facility Software Tools Manual While some material is outdated, this manual still contains a wealth of relevant …
Also see Fundamentals of SAR Media Resources How Does it Work? A synthetic aperture radar (SAR) is an active sensor that first transmits microwave signals and then receives back the signals that are returned, or backscattered, from the Earth’s surface. Flight and Directional Terminology The instrument measures the distance between the sensor and the point …

Interpretation of synthetic aperture radar (SAR) images is not always straightforward, in part because of the non-intuitive, side-looking geometry. Here are some general rules of thumb: Water Regions of calm water and other smooth surfaces appear black (the radar reflects away from the spacecraft). In the ESA image to the right of eddies around islands …
SAR: The Power Tool of Remote Sensing Synthetic aperture radar (SAR), used to create the majority of the imagery available in the ASF archive, is one of the power tools of remote sensing. Synthetic aperture radar (SAR) bounces a microwave radar signal off the Earth’s surface to detect physical properties. https://youtu.be/g-YICKbcC-A Through Snow and Rain …
