Abstract
In this study, we evaluated the relationship between the structure of an urban area and the backscattering characteristics using the CRL/NASDA airborne synthetic aperture radar (PI-SAR) which observed the Tokyo Metropolitan area, for the purpose of developing building inventory and grasping the elements of seismic risk. The specific buildings were selected from areas which show predominant intensities of HH, VH and VV polarizations. The polarization characteristics of these areas were examined from co- and cross polarization signatures computed from the PI-SAR data and were confirmed by field surveys and aerial photographs.
