A new time domain and polarimetric measurement algorithm for complex target reconstruction

With the aim of a practical validation of theoretical models, software was developed using the high-frequency-domain assumption. This permits one to construct a database of polarimetric behavior for a large number of saddle points such as dipole, infinite half-plane, tip, edge, wedge, surface wave, progressive wave, cylinder, sphere, concave surface, dihedral, trihedral, and plane surface. The inverse problem in which it becomes possible with a simple measurement of the scattering matrix to recognize the target shape is presented. All the measurements are made using a vector network analyzer with a time-domain option. With a selective time acquisition and analysis of the main saddle points of the target, information concerning distance and polarimetric behavior can be obtained. By comparison, with data calculated previously for elementary saddle points, most realistic objects can be determined. Good agreement between experimental measurements and predicted ones is observed in the X band (8-13 GHz).<>
