“…Fully polarimetric MUSIC and subspace fitting methods can improve resolution and sidelobe level, while NSF can outperform other polarimetric techniques in terms of resolution and localization of deterministic scatterers. The final solutions of the commonly adapted Capon approach is given as [9]: (6) where R ̂ is the polarimetric sample covariance matrix estimated over the spatial neighborhood of pixel of interest.…”

“…Polarimetric synthetic aperture radar (SAR) remote sensing has been used as a powerful tool for monitoring the Earth's surface, especially for creating the map to classify land use and land cover in a complex urban environment [1,2]. In the context of classification of polarimetric SAR (PolSAR) images and depending on whether reference data are used (i.e., supervised scheme) or not (i.e., unsupervised scheme), many efficient techniques have been used to assign each pixel of PolSAR data to a particular land use/land cover or backscatter mechanism [3][4][5][6][7][8].…”

This paper addresses the 3D classification of superimposed target scattering mechanisms in polarimetric synthetic aperture radar (SAR) images of urban environments. Theoretically, the solution of this problem is possible with polarimetric tomographic SAR focusing techniques. In this work, we investigate how SAR Tomography (TomoSAR) can be used to identify and distinguish the superimposed target mechanisms. In particular, various strategies are employed to separate and characterize the polarimetric scattering patterns of targets in layover regions. Extensive and comparative analyses are performed to answer how accurately different strategies can identify the polarimetric scattering pattern.
