| 摘 要： | 目标散射特性随时间变化的规律称之为目标时域散射特性。目标时域散射特征是利用多时相雷达遥感图像进行目标识别的基础。本研究以广东肇庆为试验区,利用多时相单参数雷达图像进行土地覆盖类型分类研究,分析了试验区内典型植被的结构、形态及其散射机理等特征,总结了各类目标的时域散射特性,区分识别了多种目标,制作了土地覆盖类型分类图. |
| 关 键 词： | 雷达遥感 时域散射特性 结构形态特征 |

| Abstract: | This paper presents the results of a study examining the backscatter signatures of various targets as a function of time. The characteristics of a target may show seasonal changes. If so, the backscatter signatures of the target should vary as a function of time. This serves as the basis of using multi-temporal SAR images to discriminate and classify a variety of targets. This study was carried out in Zhaoqing test site in Guangdong Province of China. The geometric characteristics of various targets and their backscattering mechanism were analyzed. The temporal backscatter of targets was emphasized and the backscatter signatures of targets as a function of time were summed up. Twelve types of land cover were classified using multi-temporal Radarsat data and, in addition, a land cover map was produced based on the classification results. |
