A Unified Coherent-Incoherent Target Decomposition Method for Polarimetric SAR

2020
Polarimetric 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 Decomposition Based on Attributed Scattering Center Model for Synthetic Aperture Radar Targets

IEEE Geoscience and Remote Sensing Letters, 2014
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 ...

Polarimetric Decomposition-Based Unified Manmade Target Scattering Characterization With Mathematical Programming Strategies

IEEE Transactions on Geoscience and Remote Sensing, 2022
Due to the orientation variation and structural complexity, designing generalized and unified features to highlight manmade target scattering from polarimetric synthetic aperture radar (PolSAR) data is challenging. Inspired by the thought of mathematical

Target Polarimetric Decompositions of PolSAR Image

2021
Target polarimetric decomposition is one of the most important aspects of polarimetric microwave imaging. The objective of polarimetric decomposition is to express the polarimetric information of the target as a combination of many known objects, such as a plate, a dihedral, a helix, a line, and a sphere, so we can understand and analyze the scattering

A Two-Step Target Decomposition Method for Polarimetric SAR based on Reflection Symmetry

IEEE Asia-Pacific Conference on Synthetic Aperture Radar, 2023
Symmetry is an important characteristic for PolSAR data. Studying the reflection symmetry of the target is conducive to simplify the study of its scattering problem. Therefore, this paper proposes a two-stage target decomposition model based on symmetry.

Polarimetric sar target decomposition based on nonlinear decorrelation

2012 Tyrrhenian Workshop on Advances in Radar and Remote Sensing (TyWRRS), 2012
In remotely sensed Synthetic Aperture Radar (SAR) images, scattering from a target is often the result of a mixture of different scattering mechanisms. Fully polarimetric data offers the possibility to separate and to interpret them. To achieve this task, several target decomposition techniques have been proposed in the literature.

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.

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 ...
