Inverse Synthetic Aperture Radar Imaging: Principles, Algorithms, and Applications

Synthetic-aperture radar (SAR) is a form of radar which is used to create images of an object, such as a landscape. SAR uses the motion of the SAR antenna over a target region to provide finer spatial resolution than is possible with conventional beam-scanning radars.

Three images – spanning more than seven years – of Titan’s Ligeia Mare in which an elusive, radar-bright feature has been spotted. Images were created from data collected by Cassini’s Synthetic Aperture Radar (SAR). Image credit: NASA/JPL-Caltech/ASI/Cornell

Synthetic Aperture Radar (SAR) imagery was acquired as part of the GeoEarthScope project. The UNAVCO Facility Data Group developed and implemented the essential infrastructure and software needed to archive the GeoES data and to support community access to this rich dataset. EarthScope InSAR data products are available from the UNAVCO Facility.

On March 17, 2013, NASAs Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) acquired synthetic aperture radar data over the Napo River in Ecuador and Peru. The image colors indicate the likelihood of inundation (flooding) beneath the forest canopy, which is difficult to determine using traditional optical sensors. Image credit: NASA/JPL-Caltech
