Learning task-driven polarimetric target decomposition: A new perspective
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Polarimetric target decomposition aims to decompose a polarimetric synthetic aperture (PolSAR) data on a base reflecting some scattering mechanisms. The corresponding coefficients will be further exploited as the feature vector for the subsequent interpretation task.

Polarimetric target scattering decomposition: A review
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016The most popular model-based decompositions (MBD) are reconsidered in the context of the estimation theory. It is shown that a large processing window is required to reduce the bias on the individual scattering contribution due the target scattering Reflection symmetry assumption.

Modification of Polarimetric SAR Interferometry Target Decomposition With Accurate Topography
IEEE Geoscience and Remote Sensing Letters, 2015In 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.

In this letter, a novel polarimetric target decomposition (PTD) method based on the attributed scattering center (ASC) model is proposed for man-made targets in synthetic aperture radar (SAR) images. By extracting attributed parameters, polarimetric characteristics of targets can be exploited by performing PTD on the extracting parameters of ASCs ...

Target decomposition for fully polarimetric wideband radar system
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010For 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 ...

Model-Based Target Scattering Decomposition of Polarimetric SAR Tomography
IEEE Transactions on Geoscience and Remote Sensing, 2018When dealing with forest scenario, target scattering separation using synthetic aperture radar (SAR) tomography is a challenging task for the application of biophysical parameter retrieval approaches. One important and widely popular solution used to investigate the scattering mechanism separation based on multipolarimetric multibaseline (MPMB) SAR ...

Polarimetric SAR Target Decomposition based on sparse NMF
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Polarimetric 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.

Migration technique can reconstruct the subsurface target imaging from record ground penetrating radar (GPR) data. Depending on the reconstructed imaging, we possibly distinguish subsurface target by the geometrical feature. But some different targets have similar reconstructed imaging, which will confuse us.

Impact of cross‐polarization isolation on polarimetric target decomposition and target detection
Radio Science, 2015AbstractCross‐polarization isolation is one of the key engineering parameters for a polarimetric radar system. Previous studies focused more on the calibration of cross‐talk contamination. This paper presents a numerical evaluation of the requirement for cross‐polarization isolation from the data users' perspective, i.e., the quantitative impact of ...

Evaluation of system polarization quality for polarimetric SAR imagery and target decomposition
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010The quality of polarimetric synthetic aperture radar (PolSAR) imagery and its polarimetric decompositions depends on the accuracy of polarimetric observations of the SAR system and its calibration. Polarization distortions on the polarimetric measurement can be incurred due to nonideal system polarization quality and propagation factors, such as ...
