Statistical Aspects of Radar Polarimetry
2004A comparison between the Kennaugh and the covariance matrix formulation of second- order moments radar and optical polarimetry reveals fundamental relationships between target decompositions and power and variance aspects of radar back scattering and transmission for point and randomly distributed targets.

Principles of Radar Polarimetry.
, 1995 Research in radar polarimetry is hampered by shortcomings of the conventional formulation of polarimetric backscatter concepts. In particular the correct form of the Sinclair backscatter matrix under changes of polarization bases is derivedfrom the ...

Basic Theory of Radar Polarimetry
2021This chapter briefly discusses Synthetic Aperture Radar (SAR) imaging principles and the theory of SAR polarimetry. The descriptions of several polarimetric parameters and their expressions are presented in this chapter. SAR imaging principles are introduced, followed by the description of wave and polarimetric scattering concepts. Several polarimetric

Polarimetry for Weather Surveillance Radars
Bulletin of the American Meteorological Society, 1999This paper is an overview of weather radar polarimetry emphasizing surveillance applications. The following potential benefits to operations are identified: improvement of quantitative precipitation measurements, discrimination of hail from rain with possible determination of sizes, identification of precipitation in winter storms, identification of ...

Radar Polarimetry for Target Discrimination
2007 IEEE Region 5 Technical Conference, 2007Discrimination of targets vs. clutter is critical to many radar identification problems. For the purpose of Improvised Explosive Device (IED) detection, radar range profiles and images are valuable to capture the target of interest; it remains a big challenge to differentiate the target from the surrounding man-made clutter.

Application Of Radar Polarimetry To Forestry
International Geoscience and Remote Sensing Symposium, 'Remote Sensing: Moving Toward the 21st Century'., 2005In order to understand L-band multipolarization radar measurements of forested areas, a model for the forest polarization signature was developed. The model is based on backscatter from dielectric cylinders which represent branches and trunks. In the model the Stokes matrices corresponding to several different scattering mechanisms is calculated ...

Radar polarimetry towards a future standardization
Annales Des Télécommunications, 1999Neuf instituts de recherche de l’Union europeenne ont reuni leurs efforts dans un projet sur la theorie et les applications de la polarimetrie radar. Bien que la polarimetrie radar soit deja prise en compte dans la definition des scenarios de teledetection de l’environnement terrestre, dans la facon d’effectuer les mesures microondes et optiques, de ...
