Characteristics Of Satellite Sar Intensity Images In Building Damage Areas Due To The 1995 Hyogo-Ken Nanbu Earthquake

摘要

Satellite and airborne remote sensing, which can easily monitor a large area with high resolution, can provide effective spatial information to detect earthquake-induced damage. As a sensor installed on satellites JERS and ERS, synthetic aperture radar (SAR) is one of the most promising technologies since it is not affected by clouds. One of distinctive characteristics of SAR systems is their capability of recording both amplitude and phase of the backscattering echoes from objects on the earth's surface. In this paper, we investigated the microwave scattering characteristics of areas damaged by the 1995 Hyogo-ken Nanbu (Kobe)earthquake using ERS/SAR images for the purpose of possibility of extracting earthquake damage distribution by satellite SAR.
