研究了星载激光测高的理论和技术,利用ICESAT测高数据确定了南极冰盖高程模型。将ICESAT测高数据与南极实测GPS数据进行比较,结果显示ICESAT数据能够很好地确定南极冰盖高程模型。
The theory and technique of spaceborne laser altimeter are studied. On this basis, using ICESAT altimeter data to determine the Antarctic ice sheet elevation model, ICESAT satellite laser altimetry data were compared with GPS data measured Antarctic expedition. ICESAT data can be used to determine the Antarctic ice sheet elevation model.
