1997 年 5 月至 1998 年 5 月，在越南湄公河三角洲的水稻种植区获取了多时相 ERS 和 RADARSAT 合成孔径雷达 (SAR) 图像。水稻种植系统的主题类别是从 ERS SAR 图像中得出的。传统双季雨养稻区的水稻种植制度发生了变化。该地区最近修建了灌溉渠，可以在旱季种植第三种灌溉作物。使用旱季期间获取的 SAR 图像检测到灌溉作物的存在。还比较了 ERS 和 RADARSAT SAR 的后向散射时间序列。
Multitemporal ERS and RADARSAT synthetic aperture radar (SAR) images were acquired over the rice cropping areas in the Mekong River Delta, Vietnam from May 1997 to May 1998. Thematic classes of rice cropping systems were derived from ERS SAR images. Change in rice cropping system in a traditionally double cropping rainfed rice area was detected. Irrigation canals were recently constructed in this area, enabling a third irrigated crop to be planted during the dry season. The presence of the irrigated crop was detected using SAR images acquired during the dry season. Backscatter time series for ERS and RADARSAT SAR were also compared.
