SAR Interferogram Phase Filtering Using Wavelet Transform
The application of SAR Interferometry (InSAR) especially in Digital Elevation Modeling as well as deformation monitoring encounters problems due to noise in the interferogram phase. The noise is mainly caused by temporal and baseline decorrelation as well as changes in atmospheric conditions that makes the process of phase reconstruction difficult and reduces the accuracy. The quality of digita...

متن کاملSAR Interferogram Phase Filtering based on the von Mises Distribution
We propose the use of the Von Mises distribution for circular data to model interferometric phase images. Based on the kappa parameter of the Von Mises distribution a locally adaptive phase filter is developed. A two-sided confidence interval on the kappa values is constructed, and only phase measurements where kappa values fall inside this interval are input to the filter We additionally put m...
متن کاملMeasurement of slow-moving along-track displacement from an efficient multiple-aperture SAR interferometry (MAI) stacking
Multiple-aperture SAR interferometry (MAI) has demonstrated outstanding measurement accuracy of along-track displacement when compared to pixel-offsettracking methods; however, measuring slow-moving (cm/year) surface displacement remains a challenge. Stacking of multi-temporal observations is a potential approach to reducing noise and increasing measurement accuracy, but it is difficult to achi...
متن کاملTopographic Mapping with Multiple Antenna SAR Interferometry: A Bayesian Model-Based Approach
Multiple-antennaSAR interferometryinvolves the use of three or more antennas to reduce the overall phase ambiguities and phase noise in interferometric data. This paper presents a Bayesian approach to topographic mapping with multiple-antenna SAR interferometry. Topographic reconstruction is formulated as a parameter estimation problem in the model-based Bayesian inference framework. An InSAR s...
