The PALSAR-2 radar is a significant upgrade of the PALSAR radar, allowing higher-resolution (1 x 3 m per pixel) spotlight modes in addition to the 10 m resolution survey mode inherited from the ALOS spacecraft. Also, the SPAISE2 automatic ship identification system and the Compact Infra Red Camera (CIRC) will provide supplementary data about ...
ALOS-2 →. Advanced Land Observing Satellite (ALOS), also called Daichi (a Japanese word meaning "land"), was a 3810 kg Japanese satellite launched in 2006. After five years of service, the satellite lost power and ceased communication with Earth, but remains in orbit.
Advanced Land Observing Satellite 4 (ALOS-4), also called Daichi 4 (daichi is a Japanese word meaning "great land"), is a 3,000 kg (6,600 lb) Japanese L-band synthetic-aperture radar (SAR) satellite that was launched on July 1, 2024. It carries PALSAR-3 (Phased Array type L-band Synthetic Aperture Radar-3), which is a successor to the PALSAR-2 ...
But in 2015, the ALOS PALSAR data became unrestricted, and the Sentinel-1 data is also unrestricted. In June 2013, the Alaska Satellite Facility released newly processed, 35-year-old data from the 1978 Seasat satellite mission. Before this release, only 20 percent of the Seasat SAR data had been processed digitally.
Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), is a radar technique used in geodesy and remote sensing.This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite [1] [2] [3] or aircraft.
ALOS-3. Advanced Land Observing Satellite 3 (ALOS-3), also called Daichi 3, was a 3-ton Japanese satellite launched on March 7 2023. It was to succeed the optical sensor PRISM (Panchromatic Remote-sensing Instruments for Stereo Mapping) carried on the ALOS satellite, which operated from 2006 to 2011. The ALOS-2 satellite and the ALOS-4 ...
Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...
JAXA's ALOS-4 launched on July 1. It carries PALSAR-3 (Phased Array type L-band Synthetic Aperture Radar-3). It carries PALSAR-3 (Phased Array type L-band Synthetic Aperture Radar-3). The European Sentinel 2C Earth observing satellite launched on 5 September.
