The use of multiple InSAR images of the same area for phase unwrapping is discussed. It is
shown that by combining the information in the two InSAR images, the ambiguity interval of …

This paper describes a new region-growing algorithm for interferometric synthetic aperture
radar (SAR) phase unwrapping. The algorithm is designed to handle noisy interferograms …

In phase unwrapping, an error made at a pixel has a tendency to spread and corrupt the
phase values over large areas of an interferogram. It is therefore important that a phase …

Phase unwrapping is the key problem in building the elevation map of a scene from
interferometric synthetic aperture radar (SAR) system data. Phase unwrapping consists in …

Phase unwrapping for SAR interferometry is one of the barriers for obtaining an operational
interferometric SAR system (InSAR). For filtering the phase one uses mainly a low pass …

SAR interferometry requires a thorough phase control throughout the imaging process. The
phase accuracy is affected by decorrelation effects between the individual surveys. The …

This paper considers the problem of unwrapping the phase image obtained from a noisy
interferometric synthetic aperture radar (InSAR) image. The implicit nonlinearity of the …

SAR interferometric surveys are affected by several sources of decorrelation noise. An
improvement of the phase accuracy can be achieved by minimizing that noise: this could …

This paper presents a new phase-unwrapping (PU) algorithm for SAR interferometry that
makes use of a particle filter (PF) to perform simultaneously noise filtering and PU. The …

Weighted least squares phase unwrapping is a robust approach to phase unwrapping that
unwraps around (rather than through) regions of corrupted phase. Currently, the only …
