Analysis and Evaluation of InSAR Phase Unwrapping Algorithm
摘要
Abstract
Phase unwrapping is the key step of InSAR data processing,the selection of phase unwrapping algorithms concern the accuracy of InSAR final result(DEM or deformation).The basic principle of phase unwrapping is introduced with eight algorithms based on path-following,minimum norm and network-flow to unwrap the interferogram over the Quebec area in Canada is unwrapped.The unwrapping results were evaluated and compared by different criteria.Experimental results prove that the Flynn minimum discontinuity method、minimum Lp norm method and the Snaphu net-work flow method have preferable stability and adaptability.关键词
