卫星雷达测高数据的坡度改正方法比较

摘要

To compare the performance of the three slope correction methods (the direct method,the indirect method and the relocation method),ERS-1 data over the Vostok region in the Antarctic are processed based on the RAMP DEM model.The results show that the relocation method performs better than the other two methods.The accuracy of the direct method is the worst in the three methods.%基于RAMP DEM模型,以南极沃斯托克地区的ERS-1数据处理为例,比较了直接法、间接法和重定位法三种坡度改正方法的精度.结果表明重定位法的精度优于其他两种方法,直接法精度最差.
