摘要

2016年，先进陆地观测卫星2号(ALOS-2，“大地二号”)对多个受灾地区进行了观测。日本宇宙航空研究开发机构(JAXA)在一年中进行了100多次紧急观测。ALOS-2搭载的相控阵型l波段合成孔径雷达2 (PALSAR-2)为灾害灾区、地表变形和洪水灾区的探测做出了贡献。特别是对于2016年日本熊本地震、新西兰凯库拉地震等破坏性地震造成的地面变形和受损区域检测，研究人员利用ALOS-2观测数据提供了变量分析结果。本文给出了一些应急观测结果的实例。

Performance of ALOS-2 PALSAR-2 for disaster response

In 2016, the Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) observed various disaster affected areas. Japan Aerospace Exploration Agency (JAXA) operated the emergency observation more than hundred times in the year. The Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard ALOS-2 contributed for detecting the disaster affected area, ground deformation and flood affected area. Especially for the ground deformation and damaged area detection caused by the devastating earthquakes in 2016, e.g., Kumamoto earthquakes in Japan and Kaikoura earthquake in New Zealand, researchers provided variable analytical results from ALOS-2 observation data. In this paper, some examples of the emergency observation results are presented.
