本文利用干涉合成孔径雷达（InSAR）数据提取了台风在日本北海道Tomakomai上空造成的森林破坏信息。通过计算台风前后两次单次x波段SAR数据的干涉图，即使没有清除倒下的树木，也可以检测到它们的高度变化，从而评估灾害程度。结果表明，InSAR分析探测到的主要破坏区域与地面真实数据吻合较好。
In this paper, interferometric synthetic aperture radar (InSAR) data are utilized to extract the forestry damage information caused by typhoon over Tomakomai, Hokkaido, Japan. By computing the interferograms of two single-pass X-band SAR data before and after the typhoon, the change of their heights could be detected even the fallen tress were not cleared, and therefore, the damage level can then be evaluated. The results show that the main damaged areas detected by InSAR analysis are in agreement with the ground truth data.
