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 presents a comparative analysis of eight phase unwrapping algorithms for SAR
interferometry that, in the opinion of the author, encompass the current" state of the art" in …

This letter presents a phase-unwrapping (PU) algorithm for synthetic aperture radar
interferometry based on a grid-based filter. The proposed PU algorithm, which is based on …

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 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 …

This paper presents a new two-dimensional (2-D) phase unwrapping (PhU) algorithm based
on a least squares (LS) region growing strategy: the wrapped phase image is partitioned in …

Phase unwrapping is the problem of reconstructing a function on a grid given its values
modulo 2/spl pi/. This is a key problem in SAR interferometry and in other fields. The typical …

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 …
