Unprocessed raw radar signals (ERS-2)

ERS-2 Level 0 Product
land NASA ASF Level 0
In plain English

What it measures. The unprocessed raw radar signals recorded by the ERS-2 satellite, before any image-making or correction has been applied.

How it's made. Captured directly by the ERS-2 radar in its standard beam mode and stored at the rawest processing stage (Level 0).

How & where you'd use it. A building-block input that specialists turn into usable radar images; most people would use higher-level products rather than this raw form.
