| Outline of Final Research Achievements |
Fully polarimetric radar is the most effective tool for monitoring disaster of the earth surface regardless of weather condition and day- and night-time. This research aimed at creating full-color radar image by own developed scattering power decomposition method for fully polarimetric radar data. The full color image is based on 4 scattering powers derived by our algorithm, and is easy to understand for everybody since each RGB color corresponds to physical scattering mechanisms such as the surface scattering, double bounce scattering, volume scattering, and helix scattering. The final color image sets of more than 2100 were uploaded to our laboratory’s website for public viewing. The fully polarimetric data sets of ALOS have been provided by JAXA. It became possible to find disaster area by color-change between pre- and post image. Almost all images in Japan and the world can be used for disaster prevention database, and will be beneficial for disaster monitoring all over the world.
