Polarimetric Decomposition With an Urban Area Descriptor for Compact Polarimetric SAR Data [PDF]

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The compact polarimetric (CP) synthetic aperture radar (SAR) can alleviate the drawbacks of the fully polarimetric (FP) SAR and provide more target information as compared to the conventional single polarimetric and dual polarimetric mode.

Polarimetric decomposition for forest biomass retrieval [PDF]

open access: yes2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
In this paper, the decomposition of fully polarimetric SAR data into three canonical scattering mechanisms is investigated with respect to forest biomass retrieval. It is demonstrated that the dominant backscattering contribution depends strongly on the frequency, incidence angle, and stand condition.

ALTERNATIVE TO FOUR-COMPONENT DECOMPOSITION FOR POLARIMETRIC SAR [PDF]

open access: yesISPRS Annals of Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
There are more unknowns than equations to solve for previous four-component decomposition methods. In this case, the nonnegative power of each scattering mechanism has to be determined with some assumptions and physical power constraints. This paper presents a new decomposition scheme, which models the measured matrix after polarimetric orientation ...

General Two-Stage Model-Based Three-Component Hybrid Compact Polarimetric SAR Decomposition Method

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Polarimetric decomposition is an effective way for synthetic aperture radar (SAR) data interpretation. As for hybrid compact polarimetric (HCP) SAR, there are mainly two different types of decomposition methods, including wave-dichotomy-theorem-based and

A type of polarimetric parameter for evaluating the reliability of model-based decomposition result and its application

open access: yesInternational Journal of Digital Earth, 2023
The reliability of the model-based decomposition result, which is seldom investigated, is a key factor in determining whether decomposition parameters can be effectively applied to polarimetric synthetic aperture radar (PolSAR) applications.
