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.
