AIRSAR Summary

AIRSAR Airborne Synthetic Aperture Radar

AIRSAR was an all-weather imaging tool able to penetrate through clouds and collect data at night. The longer wavelengths could also penetrate into the forest canopy and, in extremely dry areas, through thin sand cover and dry snow pack.

AIRSAR served as a NASA radar technology testbed for demonstrating new radar technology and acquiring data for the development of radar processing techniques and applications.
