[ABSTRACT]Scattering power decomposition theory and some images of fully polarimetric synthetic aperture radar data are presented for disaster monitoring. Utilization of fully polarimetric data can derive full color images with red-green-blue color coding, red for the double-bounce power, green for the volume scattering power, and blue for the surface scattering power, for which each color brightness corresponds to the magnitude. Since disaster causes the change of each scattering power, it becomes easy for everyone to recognize the change by color in the decomposition image when time series data sets are available. By applying the four-component scattering power decomposition to fully polarimetric data acquired with Advanced Land Observing Satellite (ALOS) Phased Array type L-band Synthetic Aperture Radar (PALSAR), we present several images for natural disaster monitoring on volcano activity, snow accumulation, land slide and tsunami effect caused by great earthquake. It is seen in the polarimetric decomposition images that most disaster areas show increasing surface scattering power compared to those in normal situations.
