Japan is a country where many disasters such as earthquakes, eruptions and typhoons occur. Therefore, in order to know the disaster’s damages globally and locally, observations by using various sensors which operated in space and on ground are carried out. Sensors using micro waves have the advantage of being able to observe day and night regardless of the weather. Among the sensors that use micro waves, a synthetic aperture radar (SAR) can produce ground images from airplane and satellite in details and is suitable for observing changes by disasters. The Japanese airborne synthetic aperture radars are Pi-SAR / Pi-SAR2. The resolution of Pi-SAR2 reaches 30cm. Japanese satellite-borne synthetic aperture radars are the advanced land observation satellites (ALOS) 1 and 2. ALOS 2 can observe same area every 14 days. These synthetic aperture radars have observed many disasters in Japan. The interferometry and polarization observation technologies based on SAR provide very useful information about the damages of disasters. In this presentation, we will introduce Japanese SARs and their observation technologies, and show the results of the Niigata Chuetsu earthquake, Kumamoto earthquake, and Mt. Ontake eruption.
Toshifumi MORIYAMA received B.E., M.E., and D.E. degrees in Information Engineering all from Niigata University, in 1994, 1995, and 1998, respectively. In his theses research, he was engaged in radar polarimetry and polarimetric radar sensing of buried objects. He was with Fujitsu System Integration Laboratories Ltd from 1998 to 2003, the National Institute of Information and Communications Technology, Japan (NICT) from 2003 to 2005, and the Earth Observation Research and Application Center (EORC), Japan Aerospace and Exploration Agency (JAXA) in 2006, respectively. He is now an associate professor at Nagasaki University. He is involved in research activities in collaboration with ELEDIA Research Center, and he is the Director of the ELEDIA@UniNAGA. His interests are in inverse scattering, radar polarimetry, microwave remote sensing, and wireless sensor networks. Currently, he is vice-chairs of IEEE Aerospace Electronics System Society Japan Chapter and IEEE Antennae and Propagation Society Fukuoka Chapter.
