摘　　要：从多源多时相遥感数据用于南极动态监测的影像获取与处理关键技术入手,针对南极过轨的卫星情况,分析了可获取的卫星影像的种类;研究分析南极在控制点缺乏以及控制点布设困难的情况下,采用无控制及稀少控制的几何纠正方法;研究分析南极遥感影像中高分辨率遥感数据光谱的使用及融合方法,为实现南极冰雪环境的动态监测提供了技术基础性分析。Based on multi-temporal remote sensing data source,the key technical analysis of dynamic monitoring in Antarctic was used to study the special geographical environment of the Antarctic,the types of satellite images were obtained by analyzing the satellite orbit over the Antarctic conditions,the geometric correction methods with no control and very few GCP(ground control points)were studied on some very difficult region in Antarctic lacking the GCP,the high-resolution spectral remote sensing images and fusion methods were used to realize the environment for the dynamic monitoring in Antarctic snow and provide the basic technical analysis.
