作者试图利用多时相RADARSAT精细模式和ERS1/SAR数据在水稻种植季节的早期估计水稻种植面积。以广岛市东部的东广岛市为试验场，利用水稻种植前后的3幅多时相RADARSAT精细模式图像和ERS-1/SAR图像作为试验数据。从RADARSAT和ERS-1/SAR数据集的前两个时间数据中，发现稻田的SAR后向散射强度显著降低。从最后两个时间数据来看，由于种植水稻的生长，SAR后向散射强度显著增加。利用RADARSAT和ERS-1/SAR数据对水稻面积估算的实际效果进行了评价，并与逐点估算的面积和统计报告的估算结果进行了比较。
The authors attempted to estimate rice-planted areas using multi-temporal RADARSAT fine-mode and ERS1/SAR data in an early period of rice-planting season. The eastern part of Hiroshima City, HigashiHiroshima City, was selected as the test field, and three multi-temporal RADARSAT fine-mode images and ERS-1/SAR images, taken before and after rice-planting were used as the test data. From the first two temporal data in RADARSAT and ERS-1/SAR data sets, SAR backscatter intensity in rice-planted fields was found to decrease significantly. From the last two temporal data, SAR backscatter intensity increased significantly due to the growth of planted rice. We evaluated the actual performance for rice area estimation by RADARSAT and ERS-1/SAR data by comparing with the estimated area by SPOT data and also with the results by the statistical report.
