Sentinel-1

The Sentinels are a new fleet of European Space Agency (ESA) satellites, developed to deliver a wealth of data and imagery central to Europe’s Copernicus program. The first in the series, Sentinel-1, includes twin satellites that each carry C-band synthetic aperture radar (SAR), together providing all-weather, day-and-night imagery of Earth’s surface.

ALOS PALSAR – About

ALOS Phased Array type L-band Synthetic Aperture Radar Mission From 2006 to 2011, PALSAR’s L-band synthetic aperture radar (SAR) yielded detailed, all-weather, day-and-night observation, as well as repeat-pass interferometry. PALSAR data are from multiple observation modes with variable polarization, resolution, swath width, and off-nadir angle. PALSAR was one of three instruments on the Advanced Land Observing …

AIRSAR

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.
