ALOS 2 [JAXA]
ALOS 2 (Advanced Land Observation Satellite 2) or Daichi 2 is a radar Earth observation satellite to be used for cartography, regional observation, disaster monitoring, and resource surveying. It is the follow up to the radar component of ALOS (Daichi).
The state-of-the-art L-band Synthetic Aperture Radar (SAR) aboard ALOS-2, which is an active microwave radar using the 1.2 GHz frequency range, which, in responding to society's needs, has enhanced performance compared to DAICHI/PALSAR. The SAR is capable of observing day and night, and in all weather conditions.
ALOS-2 has a spotlight mode (1 to 3 m) and a high resolution mode (3 to 10 m), whilst PALSAR has a 10 m resolution. It allows comprehensive monitoring of disasters by providing users with more detailed data than DAICHI/PALSAR. The observation frequency of ALOS-2 is improved by greatly expanding the observable range of the satellite up to about 3 times, through an improvement in observable areas (from 870 km to 2,320 km), as well as giving ALOS-2 a right-and-left looking function, currently not available on DAICHI/PALSAR.
