Time series evaluation for beach erosion area by satellite synthetic aperture radar analysis

在这项工作中，我检查了海岸线变化分析的潜力，并开发了海岸线跟踪方法，使用JERS-1/SAR和ALOS/PALSAR振幅图像。我还接近了集中在千叶县的九久栗滨海滩，静冈县的恩舒纳达海滩，鸟取县的鸟取沙丘，鹿儿岛县的福城滨海滩，北海道县的十胜海滩，北海道县的穆川海滩，新泻县的伊藤川海滩，以宫崎县的日向田海滩和鹿儿岛县的上之川海滩为研究对象，使用JERS-1/SAR和ALOS/PALSAR振幅图像的Kujyuukurihama海滩变化。此外，我还可以使用ALOS/PALSAR数据集，通过SAR干涉技术分析地表形变。从而为岸线追踪结果和地表变形结果分别作为空间信息提供了同步显示的方法。

In this work, I examined the potential of shoreline change analysis and developed the shoreline tracing method by using JERS-1/SAR and ALOS/PALSAR amplitude images. I also approached focusing on Kujyuukurihama beach in Chiba Prefecture, Enshunada Beach in Shizuoka prefecture, Tottori Sand Dunes in Tottori prefecture, Fukiagehama Beach in Kagoshima prefecture, Tokachi beach in Hokkaido prefecture, Mukawa beach in Hokkaido prefecture, Itoigawa beach in Niigata prefecture, Hyuuganada beach in Miyazaki prefecture and Kaminokawa beach in Kagoshima prefecture as my test site.My proposed shoreline tracing method reproduced the temporal variation of the Kujyuukurihama beach using JERS-1/SAR and ALOS/PALSAR amplitude images. Moreover, I could analysis the surface deformation by SAR Interferometry techniques using ALOS/PALSAR dataset. As a result, I could offer simultaneous display method between shoreline tracing results and surface deformation results as spatial information, repectively.
