Wildfire Progression Time Series Mapping With Interferometric Synthetic Aperture Radar (InSAR)

IEEE Geoscience and Remote Sensing Letters
We describe a novel algorithm to accurately characterize burned area and generate a time series of active burned areal extent during an actively burning wildfire based upon changes in the second-order statistics of interferometric synthetic aperture ...

On the Extension of Cameron Decomposition Helicity Asymmetry Parameter From Single-Look to Multi-Look PolSAR Imagery

IEEE Transactions on Geoscience and Remote Sensing, 2022
The helicity asymmetry parameter τ in the Cameron decomposition indicates the degree to which a scatterer deviates from being an ideal symmetric scatterer. However, the solving procedure of τ can only be expressed in terms of single-look Sinclair scattering matrix. In this paper, we extend the helicity τ to a generalized helicity parameter τg, which is

Derivation of a Signed Cameron Decomposition Asymmetry Parameter and Relationship of Cameron to Huynen Decomposition Parameters

IEEE Transactions on Geoscience and Remote Sensing, 2011
An alternate definition of the asymmetry parameter τ, appearing in the Cameron decomposition is presented. The new definition is signed as τs, but in absolute value, it is equivalent to the previous definition. The Cameron decomposition signed asymmetry parameter τs is given in terms of the Huynen decomposition parameters, including but not limited to ...

Polarimetric SAR Signature Detection Using the Cameron Decomposition

IEEE Transactions on Geoscience and Remote Sensing, 2014
An approach to the detection of specific polarimetric SAR signatures is presented. The polarimetric response in a resolution cell can be viewed as a sample of the electromagnetic scattering matrix for that resolution cell. Through the use of multiple coherent apertures, multiple samples of the scattering matrix can be obtained.

Robust discrimination of permanent scatterers using Cameron Decomposition

SPIE Proceedings, 2014
One of the main difficulties encountered in Differential Interferometry (DInSAR) applications is temporal and spatial decorrelation over time. Single pixels, called Permanent Scatterers (PS), overcome this difficulty since they are coherent over time and over wide look-angle variations.

The Equivalence Analysis for SDH Decomposition and Cameron Decomposition Based on a Unified Three-Component Scattering Model

2010 International Conference on Multimedia Technology, 2010
In 1996, Cameron proposed an approach to decompose an arbitrary polarization scattering matrix into three orthogonal components, including nonreciprocal scattering component, maximum symmetric scattering component, and minimum symmetric scattering component. In this paper, based on the analysis of the characteristics of the maximum symmetric scattering

Conservative Polarimetric Scatterers and Their Role in Incorrect Extensions of the Cameron Decomposition

IEEE Transactions on Geoscience and Remote Sensing, 2006
The properties of conservative symmetric polarimetric scatterer scattering matrices are examined. It is shown that the unambiguous rotation angle for "conservative" symmetric polarimetric scatterers is the interval (-pi/4,+pi/4] as compared with (-pi/2,+pi/2] for nonconservative symmetric scatterers.
