This contribution is devoted to characterize the shadow radiation generated by canonical three-dimensional metallic targets in the transition between far-and near-field configurations. The considered study cases take into account the essential geometrical structure of a forward scatter radar system. Results of the numerical investigations obtained through the physical-optics solution are compared with a full-wave approach based on the methods-of-moments.

In this contribution, we analyze the forward-scatter cross-section (FS-CS) of three-dimensional (3-D) metallic targets in a forward scatter radar (FSR) system, moving along arbitrary trajectories, in the transition between far- and near-field regions with respect to the receiving antenna. A vector formulation is introduced, together with a simplified approach based on a physical-optics solution of the scattering integral, and validated by means of full-wave numerical evaluations.
