3D Visualisation and Physical Feature Extraction of Urban Areas using Multibaseline POL-InSAR Data at L-Band

This paper extends two single polarization multi-baseline interferometric SAR spectral analysis techniques to the fully polarimetric configuration. These new algorithms enhance the height estimation of scatterers by calculating optimal polarization combinations and allow to determine their physical characteristics. First experimental results show the retrieval of building height and their polarimetric properties by means of single-baseline polarimetric datasets. Dual-baseline observations permit the solution of the layover problem by separating two contributions within one resolution cell. The algorithms are tested using multibaseline Pol-InSAR data acquired by DLR's E-SAR system.
