Radar images of Earth's surface (JERS-1)

JERS-1 Level 1 Product
land NASA ASF Level 1
In plain English

What it measures. Radar images of Earth's surface captured by the Japanese JERS-1 satellite. The accompanying description is minimal, so details beyond this are not provided.

How it's made. Produced from the radar instrument on the JERS-1 satellite as a basic-level data product.

How & where you'd use it. Radar imagery like this is generally used to observe land and surface features, but the limited description here doesn't specify particular applications.
