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 …
JERS-1
JERS-1 SAR Summary Mission The JERS-1 (Japanese Earth Resources Satellite) SAR is a high-resolution, all-weather imaging radar. Its primary objective was gathering data on global land masses while conducting observation for land surveys, agriculture, forestry, fisheries, environmental protection, disaster prevention, and coastal surveillance. Launch JERS-1 was launched by the Japan Aerospace Exploration Agency (JAXA), aboard …
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.
