Evaluation of Radarsat SAR data for detection of terrain features
Synergism Radarsat-SAR Optical sensor
2016/5/20
The space borne multispectral optical sensor data have been routinely used for assessment and monitoring of
natural resources and environment. One of the major problems associated with the opti...
URBAN LAND-COVER MAPPING AND CHANGE DETECTION WITH RADARSAT SAR DATA USING NEURAL NETWORK AND RULE-BASED CLASSIFIERS
Urban High resolution SAR Land use/Land cover Mapping Classification Change Detection
2016/1/3
This paper presents a new approach to extract urban landuse/land-cover information from high-resolution radar satellite data. Five-date RADARSAT fine-beam SAR images over the rural-urban fringe of the...
Detection of preparatory water in paddy irrigation area using RADARSAT/SAR-C and Landsat/ETM+
Remote Sensing Crop SAR Optical Accuracy Multitemporal

Paddy rice is one of the most important crops in Japan and it needs much water to grow, especially for water reserves for paddy
irrigation. The test site “Owari Seibu” doesn’t have enough irrigation...
Radarsat SAR的森林生物物理参数信号响应及其蓄积量估测
Radarsat SAR 蓄积量预测 树高 后向散射系数
2009/11/24
利用地面实测数据,系统探讨了Radarsat SAR 数据在森林蓄积量估测方面的应用潜力和森林生物物理参数信号响应。结果表明: Radarsat SAR后向散射系数与森林蓄积量、树高及胸径之间的关系可以用对数模型模拟; 树种对后向散射系数具有一定影响; 利
用后向散射系数估测森林蓄积量,其精度基本符合林场大面积总体估测的精度要求,但小班水平应用效果不理想。
基于RADARSAT SAR估测热带人工林叶面积指数研究
水云模型 叶面积指数(LAI) 合成孔径雷达(SAR) 后向散射系数
2009/11/23
研究了雷达后向散射系数 与热带人工林叶面积指数(LAI)的相关性。该研究通过对水云模型的修正,提出了一种半经
验性的估测热带人工林叶面积指数的方法。利用Radarsat -1 SAR数据对广东雷州人工林的验证表明,其主要林种的估测相关系数
R2接近0.5。该方法充分考虑了森林的特点以及雷达成像的特性,对于估测多云雨地区热带森林叶面积指数具有一定的参考价值。
