Joint Multi-baseline SAR Interferometry
We propose a technique to provide interferometry by combining multiple images of the same area. This technique differs from the multi-baseline approach in literature as (a) it exploits all the images simultaneously, (b) it performs a spectral shift preprocessing to remove most of the decorrelation, and (c) it exploits distributed targets. The technique is mainly intended for DEM generation at c...
متن کاملMaximum Likelihood Multi-Baseline SAR Interferometry
We propose a technique to provide interferometry by combining multiple images of the same area. This technique exploits all the images jointly and performs an optimal spectral shift pre-processing to remove most of the decorrelation for distributed targets. It’s applications are mainly for DEM generation at centimetric accuracy, and for differential interferometry. The major requirement is that...
متن کاملSingle-baseline polarimetric SAR interferometry
The objective of this paper is to examine the application of single-baseline polarimetric SAR interferometry to the remote sensing and measurement of structure over forested terrain. For this, a polarimetric coherent scattering model for vegetation cover suitable for the estimation of forest parameters from interferometric observables is introduced, discussed and validated. Based on this model,...
متن کاملA New Method for Baseline Calibration in Sar Interferometry
Synthetic aperture radar (SAR) interferometry is based on the concept of observing the same scene with two slightly different radar trajectories. It results that each point of the scene is seen from two different positions along the two radar trajectories, and the differences between those points constitute the interferometric baseline. For quantitative SAR interferometry and differential inter...
متن کاملMulti-baseline SAR Interferometry using Elaboration of Amplitude and Phase Data
Multi-baseline interferometric Synthetic Aperture Radar (In-SAR) systems can be exploited to estimate the Digital Elevation Model (DEM) of the observed scene without ambiguities and with an increased accuracy, even in the case of high sloped ground regions. The techniques usually used exploit only the interferometric phase information and they are based on Maximum Likelihood (ML) estimation. An...
