The polarization orientation angle (OA) of the scattering media affects the polarimetric radar signatures. This paper investigates the effects of orientation compensation on the coherency matrix and the scattering-model-based decompositions by Freeman-Durden and Yamaguchi et al.

A Unified Coherent-Incoherent Target Decomposition Method for Polarimetric SAR
2020Polarimetric SAR decomposition is an effective tool to extract ground scattering components and it was dedicated to coherent or incoherent situations. However, coherent targets always mix with incoherent targets in a real situation, which makes decomposition a challenging task.

Polarimetric target matrix decompositions and the 'Karhunen-Loeve expansion'
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003This contribution is concerned with polarimetric target matrix decomposition theorems for incoherent backscattering from distributed targets described by complex random 2/spl times/2 Sinclair matrices. The polarimetric covariance matrix concept is used to establish connections between the target decomposition theorems of Cloude and Barnes-Holm and the ...

Target decomposition and polarimetric radar applied to concealed threat detection
SPIE Proceedings, 2013Target decomposition is of interest to the security and defence community as it enables data sets to be reduced to their principal identifying components as a pre-processor to running pattern recognition algorithms. An investigation into the application of target decomposition theory for concealed threat detection is presented.

Improved Four-Component Model-Based Target Decomposition for Polarimetric SAR Data
IEEE Geoscience and Remote Sensing Letters, 2012An improved four-component model-based target decomposition scheme for polarimetric synthetic aperture radar data is proposed in this letter. The reason for the emergence of the negative powers in the Yamaguchi decomposition has been analyzed, and three corresponding additional steps are added in the proposed scheme.

In this paper a decomposition scheme for analysis and classification of statistical radar targets is presented. For this purpose eigenvector target decomposition (ETD) analysis method is used for calculating coherency eigenvalues. Also a simulation scheme is developed for calculating entropy, scattering mechanism for discrimination of several surface ...

Target Detection and Characterization using H/alpha Decomposition and Polarimetric Signatures
2006 2nd International Conference on Information & Communication Technologies, 2006Recently, the characterization and classification of terrain-cover using polarimetric SAR data has been extensively investigated and reported on (J.S.Lee, 1994). In this paper we re-examine the entropy-alpha approach (J.S.Lee, 1999) to radar polarimetry and show how the basic method may be augmented by the addition of the polarimetric signature ...

For detecting the deterministic targets in polarimetric synthetic aperture imagery, an improved method is suggested in this paper. A concise introduction is put forward about the principle of detecting single targets using polarimetric fork at first. The first drawback of the classic method is that the threshold of coherence can not be automatically ...
