+# Processing Synthetic Aperture Radar (SAR) Data in Azure
 
 SAR is a form of radar that is used to create two-dimensional images of three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target to provide finer spatial resolution than conventional stationary beam-scanning radars.
