We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (s11 ements are...
InSAR与ICEsat测高技术作为极具潜力的两项对地观测技术，各有其特点，利用卫星激光测高数据对星载SAR干涉测量DEM进行倾斜改正具有十分重要的意义，为提取无控制特殊困难地区大范围DEM提供了一种全新的方法。本文介绍了InSAR与ICEsat激光测高两种技术的特点及互补性；分析了利用ICEsat测高数据改正InSAR数据本身难以消除的误差的可行性；并以南极Grove山大范围DEM的提取为例，证...
