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).

An Incoherent Decomposition Algorithm Based on Polarimetric Symmetry for Multilook Polarimetric SAR Data

IEEE Transactions on Geoscience and Remote Sensing, 2020
Polarimetric symmetry, including reflection symmetry, rotation symmetry, and azimuthal symmetry, are useful concepts for describing the scattering characteristics of polarimetric synthetic aperture radar (SAR) data. In this study, for the coherency matrices of multilook polarimetric SAR data, three new scattering models were first proposed based on the

Analysis of polarimetric vessel signatures in SAR image based on polarimetric decomposition

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
In this paper, vessel characterization is investigated using fully polarimetric Radarsat-2 SAR data. Polarimetric decompositions, including coherent decompositions, decomposition based on eigenvector analysis and model based decomposition, are applied to the quad-pol data to investigate vessel's scattering mechanism.

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

A new compact polarimetric SAR decomposition technique

Remote Sensing Letters, 2015
In this paper, we have proposed a new decomposition technique for compact polarimetric (CP) synthetic aperture radar (SAR) data. In the proposed decomposition, the odd and the even bounce scattering powers and are, respectively, obtained by combining the powers received in the opposite-sense circular (OC) polarization and the same-sense circular (SC ...

Polarimetric-anisotropic decomposition of synthetic aperture radar

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
To explore anisotropic information embedded among sub-aperture SAR images, we propose polarimetric sub-aperture singular value decomposition, where polarimetric and anisotropic features are simultaneously decomposed. The decomposed singular values and left singular vectors are equivalent to eigen-analysis-based polarimetric target decomposition, while ...

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 ...

Unsupervised classification using polarimetric decomposition and complex Wishart classifier

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
The authors propose a new method for unsupervised classification of terrain types and man-made objects using polarimetric synthetic aperture radar (SAR) data. This technique is a combination of the unsupervised classification based on polarimetric target decomposition, S.R. Cloude et al.
