The Ministry of Economy, Trade, and Industry (METI) and Japan Aerospace Exploration Agency (JAXA) would like to announce that image data was successfully acquired by the Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard the Advanced Land Observing Satellite "Daichi," which was launched on January 24, 2006 (Japan Standard Time, JST). The data was acquired as part of the initial functional verification test.
The attached images of Mt. Fuji and Izu Peninsular (Diagram 1) and Shizuoka City (Diagram 2) were observed by the PALSAR at 10:16 p.m. on Feb. 15 (JST), and later received at the Earth Observation Center (in Hatoyama-cho, Hiki-gun, Saitama Pref.)
The PALSAR is the only satellite that uses onboard phased array type synthetic aperture radar with L-band by which observations are less affected by conditions on the earth's surface. By observing the same location on the earth twice (interference processing), the observation accuracy for the elevation and subsidence on the earth can be as close as a few centimeters.
Note: The PALSAR was developed by the METI in cooperation with JAXA. At the METI, the Japan Resources Observation System Organization (JAROS) is in charge of developing the electric equipment, and the Earth Remote Sensing Data Analysis Center (ERSDAC) is in charge of data processing and its use and research.
|The PALSAR is an upgraded Synthetic Aperture Radar (SAR) onboard the Japan Earth Resources Satellite-1 (JERS-1) with improved function and performance. It is an active type microwave sensor which can carry our observations day and night regardless of weather conditions. The PALSAR is equipped with a function to change its observation direction and observation mode to cover wider range (Scan SAR.) The radar is developed in cooperation with the Japan Resources Observation System Organization (JAROS) of the Ministry of Economy, Trade and Industry (METI.)
