基于质量引导的InSAR快速相位解缠方法
Fast phase unwrapping method based on quality guide for InSAR
摘要
Abstract
The traditional quality guide phase unwrapping method is unefficient because of a great deal of sort operations in the process of phase unwrapping, especially for large InSAR phase data. This paper proposes a method of index fragmentation heap sort wrapped phase unwrapping. This method puts QPDVC as quality figure in order to combine with the advantages of traditional quality figure, and uses the index fragmentation heap sort to divide large phase data into some small heaps, saving the time of adjusting to mimimum heap in sort process. Compared with traditional methods, this method improves the unwrapping accuracy and efficiency. Finally, the simulation results show that the method is effective and feasible.关键词
