基于聚类分析多通道InSAR联合相位解缠算法
Multi-Channel InSAR Phase Unwrapping Method Based on Cluster-Analysis
摘要
Abstract
Multi-channel phase unwrapping method can break the limitation of phase continuity as-sumption.So it has an advantage in the recovery of the absolute phase in complicated areas.However, multi-channel phase unwrapping processes more than one interferogram,which will bring great pressure on execution speed and memory.Multi-channel phase-unwrapping algorithm based on cluster-analysis (CA) performs well on execution speed,but it has poor robustness.So a new phase unwrapping method combi-ning the CA algorithm with the region expansion is proposed.First,it takes the edge curves of interfero-gram by edge extraction operator,unwraps the edge curves based on CA algorithms,and then regards the unwrapping edge curves as the seeds for region expansion.According to the experiments on the simulated and real multi-baseline InSAR dataset,the efficiency and effectiveness of this method are tested.关键词
