چکیده

Based on the Kennaugh-Huynen decomposition, the Target Scattering Vector Model (TSVM) allows to extract four rollinvariant parameters. Those parameters are necessary for an unambiguous description of the target scattering mechanism. The proposed method consists in applying the TSVM prior to the GLRT-LQ detector for the detection of any oriented target.

[hal-00661711, v1] Bistatic Polarimetric SAR Decomposition in Terms of Roll-Invariant Parameters

This paper introduces a new bistatic Polarimetric SAR decomposition in terms of roll-invariant parameters. The proposed decomposition is an extension of the Target Scattering Vector Model to the bistatic case, where the cross-polarization terms of the scattering matrix are not necessary equal.

Heterogeneous Clutter Models for Change Detection in Polsar Imagery

The new generation of Synthetic Aperture Radar (RADARSAT-2, TerraSAR-X, ALOS, . . . ) allows us to capture Earth surface images with very high resolution. Therefore the possibility to characterize objects has become more and more attainable. Moreover, the short revisit time propertie of these satellites enables the development of techniques of change detection and their applications. Sphericall...

Estimation of Normalized Coherency Matrix through the Sirv Model. Application to High Resolution Polsar Data

In the context of non-Gaussian polarimetric clutter models, this paper presents an application of the recent advances in the field of Spherically Invariant Random Vectors (SIRV) modelling for coherency matrix estimation in heterogeneous clutter. The complete description of the POLSAR data set is achieved by estimating the span and the normalized coherency independently. The normalized coherency...

تخمین وفقی مرز کلاتر در کلاتر‌های ویبول با استفاده از پیش آشکارساز UMPI

In radar detection, the existence of the clutter edge in the reference samples considerably degrades the performance of the detector. Hence, clutter edge estimation not only improves the CFAR detectors, but also can be used for partitioning the various areas of the clutter in the clutter map. In this paper, we propose an adaptive algorithm for detecting the clutter edge between two Weibull clut...

[hal-00520554, v1] Extension of the Target Scattering Vector Model to the Bistatic Case

The polarimetric information has been widely used to interpret the Synthetic Aperture Radar (SAR) scene. Hence, many decompositions have been introduced to extract polarimetric parameters with a physical meaning. Nevertheless, for most of them, the reciprocity assumption is assumed. For a bistatic PolSAR sensor, the cross-polarization terms of the scattering matrix are not equal. This paper pre...
