Airborne radar brightness maps of the ground (UAVSAR)

UAVSAR_INSAR_AMPLITUDE_GRD
deformation NASA ASF Level 1 active
In plain English

What it measures. How brightly the ground reflects radar signals back to an aircraft, shown as an image laid onto the ground. Brighter areas bounced more radar energy back.

How it's made. Collected by the airborne UAVSAR radar instrument during repeat flights, then projected onto the ground. The abstract is brief, so details are limited.

How & where you'd use it. A lower-level radar image typically used as input for further radar analysis, such as detecting ground changes between flights, rather than viewed on its own.
