Abstract
Three different types of space borne SAR data were processed and analyzed to investigate temporal changes of SAR backscattering intensity of riceplanted fields. The result clearly indicated the superiority of C-band SAR by RADARSAT/FINE and ERS-1 compared with L-band SAR by JERS-1 for the purpose of rice monitoring. Next, rice-planted area estimation in whole Higashi-Hiroshima City was attempted by using RADARSAT/FINE and ERS-1/SAR and the results coincided well with the statistical values by the government office. In addition, a possibility for riceplanted area estimation in an early stage, namely just after rice-planting season, was also suggested from the result of this study.
