In plain English
What it measures. Radar imagery of the land surface that captures not just brightness but also surface texture and structure, by sending out radar pulses and recording how they bounce back in different polarizations.
How it's made. Gathered by UAVSAR, an aircraft-mounted radar flown on a NASA G-III plane, with the scene projected onto a map grid.
How & where you'd use it. Useful for mapping terrain, vegetation, soil, and ground changes; the abstract is sparse, but radar like this typically supports studies of land surface conditions and deformation.
