Full polarimetric GPR data decomposition and imaging

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Polarization is a property of electromagnetic wave that generally refers to the orientation of the electric field vector, which can be used to characterize target properties by polarimetric radar. Polarimetric decomposition methods have been common in the terrain and land-use classification based on plolarimetric synthetic aperture radar data. However,

Biomass retrieval based on polarimetric target decomposition

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Former NASA's Deformation, Ecosystem Structure, and Dynamics of Ice (DESDynI) satellite mission was to provide regional or global biomass carbon stock at regional, national, and global scales. Carbon Monitoring System UAVSAR and LVIS data acquired in August 2009 were used in this paper.

Polarimetric target scattering decomposition: A review

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
The 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.

Application of freeman decomposition to full polarimetric GPR

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Full-polarimetric Ground-penetrating radar (GPR) is considered as a promising sensor for detecting buried targets. However, the polarimetric decomposition technique plays a crucial role in identifying and classifying targets which are buried in the sand under the surface.

Coherent Decomposition of Fully Polarimetric Radar Data

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
This paper presents a coherent decomposition scheme for a few scattering matrix data. A simple model-fitting decomposition method is applied to retrieve scattering mechanism or identify scatterers based on the coherency matrix. The decomposition results are compared with some experimental data obtained by fully polarimetric FM-CW radar. It is shown the

Model-based polarimetric scattering decomposition for TomoSAR

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
SAR Tomography, or TomoSAR, is one of the powerful SAR data analysis tool with multi-baseline data set, especially for height estimation of scattering centers. On the other hand, PolSAR, or Polarimetric SAR, is also powerful tool for scattering characteristic discrimination of terrain. Several PolSAR analyses have applied to the TomoSAR.

Bistatic polarimetric decompositions applied to depolarizing targets

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
This paper deals with the behavior of the depolarization of natural environments in bistatic settings. In bistatic radar imaging, we seek simulation tools capable of predicting this depolarization for any geometric configuration. As we lack actual real data to validate such tools, we propose an alternative measurement method, at the optical scale, on ...

Polarimetric Decomposition for Monitoring Crop Growth Status

IEEE Geoscience and Remote Sensing Letters, 2016
This letter investigates the polarimetric decomposition for monitoring the crop growth status over agricultural fields. Based on an existing polarimetric decomposition, the vegetation volume scattering component is removed from the full polarimetric synthetic aperture radar (SAR).

Polarimetric Calibration Based on Lexicographic-Basis Decomposition

IEEE Geoscience and Remote Sensing Letters, 2016
A novel polarimetric calibration scheme on the basis of lexicographic matrix decomposition is proposed, and a new polarimetric active radar calibrator (PARC) with two independently rotatable antennas is designed to obtain the lexicographic matrices. Thus, the proposed method is realizable and can operate with the lexicographic target vectors instead of
