Comparison of Global and Local Approach to Phase Unwrapping for Rugged Terrain
نویسنده
چکیده
RESUME Phase unwrapping is the most informal step of the interferometric SAR processing for calculation of digital elevation model. Present algorithms use two ways for resolving this problem: local and global approach. In this paper we analyze efficacy of three phase unwrapping methods (and their modifications) using standard ERS SAR scene for the Baikal Lake region (the Barguzin valley with mountainous surrounding). We estimate advantages and disadvantages of both approaches .

InSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space
Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...

This paper presents a new efficient algorithm of filtering and unwrapping phase images for interferometric synthetic aperture radar (InSAR) based on nonlinear phase model. First, we analyzed the statistical and signal properties of interferometric phase, and proposed the concept of nonlinear phase model. The model of reflecting topographic contour is used to approximate the interferometric phas...

By today, the technology of synthetic aperture radar (SAR) interferometry (InSAR) has been largely exploited in digital elevation model (DEM) generation and deformation mapping. Conventional InSAR technique exploits two SAR images acquired from slightly different angles, in which the information of elevation and deformation can be captured through processing of the phase difference of the image...

In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
