Airborne radar imaging in three frequencies (AIRSAR)
AIRSAR_POLSAR_SYNOPTIC_3_FREQ_POLARIMETRY
land NASA ASF Level 1
In plain English
What it measures. Radar images of the land captured at three different radar frequencies and in full polarization, giving multiple views of surface texture and structure.
How it's made. Collected by the AIRSAR radar instrument flown aboard a DC-8 aircraft rather than a satellite, as a synoptic three-frequency product.
How & where you'd use it. The abstract is sparse, but this kind of multi-frequency radar imagery is typically used to study land surfaces, vegetation, and terrain from the air.
