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

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 …

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

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 …

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 …

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

Phase unwrapping is the reconstruction of a function on a grid given its values mod 2/spl pi/.
Phase unwrapping is a key problem in all quantitative applications of synthetic aperture …

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 …
