چکیده

Synthetic aperture radar interferometry (InSAR) is an important remote sensing technique to retrieve the terrain digital elevation model (DEM)[1][2]. Image coregistration, InSAR interferometric phase estimation (or noise filtering) and interferometric phase unwrapping[3][4][5][6] are three key processing procedures of InSAR. It is well known that the performance of interferometric phase estimation suffers seriously from poor image coregistration.

An estimation method for InSAR interferometric phase using correlation weight joint subspace projection

In this article, we propose a method to estimate the synthetic aperture radar interferometry (InSAR) interferometric phase based on the model of correlation weight joint pixel by using the joint subspace projection technique. In the method, the correlation weight joint data vector is constructed and the data vector can make the noise subspace dimension of the corresponding weight covariance mat...

Optical and Radar Data Fusion for Dem Generation

This paper presents a DEM generation procedure based on optical (SPOT stereo) and radar (InSAR, interferometric SAR) data. The first part of the paper is focused on InSAR. The second one is concerned with the integration of optical and radar data. Two levels of integration are proposed: the SPOT data can support the InSAR procedure (in particular phase unwrapping) and the SPOT and InSAR data ca...

ALOS−PalSAR Pol−InSAR Data Analysis: First Results

This paper presents a first calibration and quality analysis of Pol−InSAR data acquired by the ALOS−PalSAR based on deterministic and extended scatterers. The calibration of Pol−InSAR data requires the estimation and compensation of polarimeteric and interferometric system and propagation (through the ionosphere and atmosphere) induced distortions. Constant phase errors/offsets appear in the po...

Insar Phase Unwrapping: a Polarimetric Approach

Polarimetric interferometric SAR data analysis is a helpful tool to discriminate the different kinds of artefacts. Most of them are encountered over volume areas, under the form of a phase centre bias. Recently, many studies have been proposed to estimate the interferometric phase over forest areas (Papathanassiou and Cloude (1), Yamada et al. (2)). One of them is based on the ESPRIT (Estimatio...

Tree Height Estimation from Multi-temporal Ers Sar Interferometric Phase

Multi-temporal sets of ERS-1/2 SAR interferometric (InSAR) phase have been evaluated at several test sites in Europe for tree height estimation. Atmospheric artefacts affected a large number of image pairs. These were generally well compensated in case of large-scale artefacts over small forests, whereas for large forests their effect could only be assessed. Hence, the amount of pairs utilizabl...
