PolInSAR Coherence Set Theory and Application
In this paper we investigate coherence sets in polarimetric SAR interferometry. The coherence set is closely related to the numerical range (field of values). This paper aims to bring the numerical range to the attention of the radar research community. The mathematical understanding of the numerical range helps to understand theoretical and physical properties of coherence and coherency matrix...
متن کاملANALYSIS OF SCATTERING CERTERS’ SEPARATION BY POLinSAR COHERENCE OPTIMIZATION
Coherence optimization in Polarimetric SAR Interferometry is expected to distinguish scatters separated in height. However, it is not easy to provide physical explanation for those optimized results. According to a coherent decomposition theorem, normalized vectors corresponding to Sphere, Diplane and Helix (SDH) scattering mechanisms respectively are obtained. Based on the interferogram phase ...
متن کاملForest Height Extraction from PolInSAR Image Using a Hybrid Method
Forest height is one of the most important vegetation vertical structure for many forest management activities. It is closely related with forest biomass and absorption of carbon. PolInSAR is a promising remote sensing technique that has been frequently used for extracting forest height. Recently, there have been plenty of research on the retrieval of vegetation parameters by single frequency s...
متن کاملOn Multibaseline Polarimetric Interferometric Techniques for Natural Media
Within the framework of the DRAGON project, a study of Polarimetric SAR Interferometry (PolInSAR) techniques for forests, and natural media in general, has been conducted. This paper focuses on two points. The first is a review of a general PolInSAR coherence model with respect to polarization diversity. The coherence constituents are identified and examined. The second part introduces two gene...
متن کاملThe Dependence of the Polinsar Degree of Coherence on Forest Parameters
Understanding the dependence of observables on biophysical parameters is crucial for a correct exploitation of the information embedded in the SAR data. In this contribution we report on the sensitiveness that the polarimetric and interferometric phase presents versus forest parameters. Different characteristics of the acquisition sensor are also included in the analysis. We use a detailed cohe...
