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

在这项工作中，我研究了海岸线变化分析的潜力，并利用JERS-1/SAR和ALOS/PALSAR振幅图像开发了海岸线跟踪方法。我还把千叶县的久久里滨海滩、静冈县的恩顺田海滩、鸟取县的鸟取沙丘海滩、鹿儿岛县的福岛滨海滩、北海道的德胜海滩、北海道的武川海滩、新泻县的伊藤川海滩、宫崎县的hyuganada海滩和鹿儿岛县的神奈川海滩作为我的测试地点。我提出的海岸线追踪方法利用JERS-1/SAR和ALOS/PALSAR振幅图像再现了Kujyuukurihama海滩的时间变化。利用ALOS/PALSAR数据集，利用SAR干涉测量技术对地表变形进行分析。因此，我可以提供海岸线追踪结果和地表变形结果分别作为空间信息同时显示的方法。

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.
