Reconstruction of the 3D Stereo Buildings from Polarimetric SAR Images in Two Converse Flights

The height and location of the three dimensional (3D) objects can be retrieved from polarimetric SAR images in multidirectional flights, and the 3D stereo objects can then be reconstructed. Polarimetric SAR image describes the objects via polarization synthesis, and presents much richer information than mono-polarized SAR image. Furthermore, multi-aspect flights of polarimetric SAR can see the 3D stereo objects in different angles and become feasible to invert the height and location of the objects. This paper presents an attractable approach for reconstruction of the 3D stereo buildings from two converse flights of airborne PI-SAR images (at X band with spatial resolution 1.5 m).
