Multi-aspect POL-InSAR 3D Urban Scene Reconstruction at L-Band

This paper generalizes a multibaseline interferometric SAR signal model to the polarimetric scenario. Based on this formulation, three spectral analysis techniques are adapted to process multibaseline POL-InSAR observations. These new methods enhance the height estimation of scatterers by calculating optimal polarization combinations and allow the determination of their polarimetric reflectivities and physical characteristics. Building layover is analyzed by producing three-dimensional images from polarimetric dual-baseline InSAR measurements. The dataset has been acquired by DLR's E-SAR system over Dresden city.
