Any method that permits retrieving full range (unwrapped) phase values starting from their (-
/spl pi/,/spl pi/) determination (wrapped phase) can be defined as a phase unwrapping …

The growing interest in the applications of synthetic aperture radar (SAR) interferometry led
to an increasing demand for reliable phase unwrapping techniques. Research efforts have …

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 …

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 …

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 …

In the SAR community there are many methods offered for solving the problem of
unwrapping the phase obtained from a noisy interferometric SAR (InSAR) image [2-5] …

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 …

Phase unwrapping is usually considered for data defined on a rectangular grid. In this
article, the case in which data are available on a sparse set of points is considered. The …

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 …

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