[hal-00520554, v1] Extension of the Target Scattering Vector Model to the Bistatic Case
نویسنده
چکیده
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 presents a generalization of the Target Scattering Vector Model (TSVM) to the bistatic case.

[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.
متن کامل[hal-00520566, v1] Roll Invariant Target Detection based on PolSAR Clutter Models
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.
متن کاملExtension and Validation of an Advanced Integral Equation Model for Bistatic Scattering from Rough Surfaces
This paper deals with the modeling of bistatic scattering from a randomly rough surface. An advanced integral equation model is presented by giving its general framework of model developments, model expressions, and predictions of bistatic scattering for various surface parameters. Extension work to improve the model accuracy is also reported in more detail. In particular, the transition functi...
متن کاملTarget Detection in Bistatic Passive Radars by Using Adaptive Processing Based on Correntropy Cost Function
In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...
متن کاملPolarimetric bistatic radar scattering behavior of the ocean surface
this paper points out the frequency dependence on the polarimetric radar scattering behavior of the ocean surface in the frequency range 1-18 GHz (Lto Ku-band). We treat this problem with a unifying scattering model named Small Slope Approximation (SSA) to evaluate the Normalized Radar Cross Section (NRCS). The calculations were made by assuming the surface-height spectrum of Elfouhaily et al f...
