摘　　要：时空模型有助于人们获取类似于真实世界的时间及空间信息 ,对于城市工程设计、灾害预防决策及军事应用具有重要意义。本文探讨了机载SAR影像重构时空模型的潜力及方法 ,研究了时空模型重构因子、基于机载SAR影像的建筑物、植被的三维提取 。Spatio-temporal model,for people,can make it easy to obtain temporal and spatial information just like the true world,and it is of much importance to the planning and designing of civil engineering,the directing of disaster prevention and the plotting of military action.In this paper,the method and the potential of utilizing airborne SAR imagery to retrieve the temporal and spatial information were discussed.It researches the primary factors to reconstruct the spatio-temporal model,the three dimension (3D) reconstruction of buildings and vegetation from high resolution airborne SAR imagery,and corresponding method of spatio-temporal modeling from airborne SAR imagery.
