HIGH RESOLUTION SAR IMAGING EMPLOYING GEOMETRIC FEATURES FOR EXTRACTING SEISMIC DAMAGE OF BUILDINGS
SAR Imaging Geometry Feature Building Seismic Damage Extraction
2018/5/11
Synthetic Aperture Radar (SAR) image is relatively easy to acquire but difficult for interpretation. This paper probes how to identify seismic damage of building using geometric features of SAR. The S...
ESTIMATION OF SURFACE DEFORMATION DUE TO PASNI EARTHQUAKE USING SAR INTERFEROMETRY
InSAR Surface Deformation Sentinet-1 Earthquake Pasni
2018/5/11
Earthquake cause ground deformation in sedimented surface areas like Pasni and that is a hazard. Such earthquake induced ground displacements can seriously damage building structures. On 7 February 20...

本文以ALOS卫星PALSAR影像为数据源,采用强度图像偏移量方法获得的整个汶川地震地表二维形变场显示,整个映秀-北川地表破裂带全长约240 km,从西南端的虹口往北东方向一直延伸到青川县附近,在虹口及北川县城所在地为两个形变量最大区域,偏移量可达4~6 m,局部更是达到了6~8 m.在高川乡附近出现一斜列拉分阶区,宽约8~10 km.在映秀-北川断层的地表破裂迹线南侧约12 km处还有一条汉旺-...
星载SAR差分干涉测量提取汶川地震同震形变场
差分干涉测量 汶川地震 地震形变
2013/9/25
采用合成孔径雷达差分干涉测量技术对2008年5月12日四川汶川地震(Ms=8.0)的形变信息进行了提取,并开展了研究,利用地震前后ALOS/PALSAR数据,进行重复轨道差分干涉处理,得到了震前—震后的干涉条纹图和形变结果图.由雷达视向形变图可知,此次地震造成了隆起形变,最大形变出现在北川—映秀断裂带上,最大雷达视向形变量超过了90 cm,形变范围较大,川西的大部分地方都出现了不同程度的地表形变....
Kinematics of the November 12, 1999 (Mw=7.2) Düzce Earthquake Deduced from SAR Interferometry
Düzce earthquake SAR Interferometry GPS elastic modelling source parameters
2009/7/8
On November 12 1999, a destructive earthquake struck the Düzce area, following the 17 August 1999 İzmit earthquake that had occurred to the west about 3 months earlier. The Mw=7.2 Düzce earthqua...
