Abstract :
Interferometric baseline plays a very important role in InSAR data processing, and it will directly affect the accuracy of interferometric result. In this article, three classical baseline estimation methods were described. By comparing and combining three methods, a new baseline estimation method and its flow were listed. RADARSAT-2 satellite image data and grid digital elevation model ASTER GDEM (30m resolution) in Kailuan area are used as sample data. By analyzing the differential interferometric results generated with different baseline estimation methods, it can be concluded that the new method used by this article is correct and feasible.
