Target decomposition for fully polarimetric wideband radar system

IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010
For fully polarimetric wideband radar system, a novel method of radar target recognition using polarimetric feature is proposed. First, polarimetric scattering matrix is obtained from fully polarimetric high resolution range profiles(HRRPs). Then, two different kinds of polarimetric features are extracted by polarimetric target decomposition theorem ...

Polarimetric SAR Target Decomposition based on sparse NMF

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Polarimetric Targets Decomposition is to decompose polarimetric data into several components by different physical scattering mechanism. Traditional decomposition methods are model-based, whose basis matrix is fixed to typical physical scatterers, such as surface, double bounce, volume.

Super-Resolution of Polarimetric SAR Images Based on Target Decomposition and Polarimetric Spatial Correlation

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Polarimetric SAR (PolSAR) is becoming more and more popular in remote sensing research area. Super-resolution processing of PolSAR image is usually desired for PolSAR image applications, such as image interpretation and target detection. Usually in a PolSAR image, each resolution contains several different scattering mechanisms. If these mechanisms can

Modification of Polarimetric SAR Interferometry Target Decomposition With Accurate Topography

IEEE Geoscience and Remote Sensing Letters, 2015
In this letter, an accurate topographical phase is applied to the model-based (odd-bounce, double-bounce, and volume scattering) decomposition of synthetic aperture radar (SAR) interferometry data. The decomposition procedure considered here is a determined nonlinear equation system that can be solved numerically.
