摘要/Abstract

摘要： 相位解缠是干涉测量的重要处理步骤之一，随着观测技术的进步，解缠处理也面临着新的情况，尤其是针对大块、海量数据的处理问题。本文提出了一种基于界面传播的并行相位解缠方法，首先利用残差点和数据质量指标分布定义数据的可靠度，然后根据可靠度的取值解算绝对相位。整个过程的实现基于数据分块的并行处理模式，数据块内与块间的操作实现了界面正向和反向传播过程。真实InSAR数据试验结果验证了本文方法的可靠性和高效性。

Abstract: Phase unwrapping is one of the important processing steps of interferometric measurement.With the progress of observation technology,the unwrapping process is also facing new situation,especially for large and massive data processing problems.In this paper,a parallel phase unwrapping method based on interface propagation is proposed.Firstly,the reliability of the data is defined by the residual point and the distribution of the data quality index,and then the absolute phase is calculated according to the reliability value.The realization of the whole process is based on the parallel processing mode of data block,and the operation between the data blocks and the block realizes the interface forward and reverse propagation process.The experimental results of real InSAR data verify the reliability and efficiency of the proposed method.

Key words: interface propagation, phase unwrapping, parallel acceleration
