Polarimetric response for target characterization

چکیده
ABSTRACT: In this paper we propose the polarimetric response in target characterization and SAR radar image classification. Polarimetric response is a graphical representation that is dependent on transmitted and received polarizations. The polarimetric response is given in a pair of two curves, one represents the copolarized response and the second represents the cross-polarized response. The fully polarimetric data is a combination of linear polarizations (HH, HV, VH and VV). This data must be structured in the form of 2*2 complex matrix known as the scattering matrix. The generation of polarimetric response needs the knowledge of the scattering matrix. It is called polarization synthesis. In this paper we give different polarimetric responses that characterize canonical targets such as the dihedral or the sphere as well as the polarimetric response of distributed targets such as forests.

Interest in urban feature characterization has increased with the potential of polarimetric satellite SAR data from ALOS (already in orbit), Radarsat-2, TerraSAR, and Cosmo-SkyMed. The Touzi-Decomposition [1] has been introduced for both coherent and incoherent decomposition of target scattering using polarimetric SAR data. In contrast to the existing scattering decompositions [2, 3], the Touzi...

On 10 August 2016 China launched the GF-3, its first C-band polarimetric synthetic aperture radar (SAR) satellite, which was put into operation at the end of January, 2017. GF-3 polarimetric SAR has many advantages such as high resolution and multi-polarization imaging capabilities. Polarimetric SAR can fully characterize the backscatter property of targets, and thus it is of great interest to ...

Conventional polarimetric linear polarized systems permit separate routage of the cross-polarized HV and VH voltage to the same receiver, and this offer the possibility of the improvement of the cross-polarized return of 6 to 9 dB in term of signal to noise ratio (S...

In addition to spectral information acquired by traditional multi/hyperspectral systems, passive electro optical and infrared (EO/IR) polarimetric sensors also measure the polarization response of different materials in the scene. Such an imaging modality can be useful in improving surface characterization; however, the characteristics of polarimetric systems have not been completely explored b...
