摘要

为了将现有的基于c波段SAR的震害估计模型扩展到l波段SAR，本文以1995年神户地震的JERS-1/SAR (l波段SAR)图像及其详细的地面真值数据为基础，引入似然函数估算地震严重震害比。该模型应用于1993年日本北海道南sei-oki地震海啸灾区的JERS-1/SAR图像。

Estimation of building damage ratio due to earthquakes and tsunamis using satellite SAR imagery

In order to expand the existing C-band SAR based damage estimation model into L-band SAR, this paper introduces a likelihood function to estimate severe damage ratio by earthquakes on the basis of dataset from JERS-1/SAR (L-band SAR) images observed the 1995 Kobe earthquake and its detailed ground truth data. The model is applied to JERS-1/SAR images taken over the tsunami affected areas by the 1993 Hokkaido Nansei-oki, Japan earthquake.
