An Improved SBR-based 3-D Scattering Center Modeling Algorithm for Wideband RCS Reconstruction

This paper proposes an improved three-dimensional (3-D) scattering center (SC) modeling algorithm using the shooting and bouncing ray (SBR) technique to achieve high precision with relatively low time consumption and memory footprint. The scattering center model (SCM) efficiently established by the improved algorithm can be applied to realize effective wideband radar cross section (RCS) reconstruction. To demonstrate the RCS reconstruction performance of the proposed algorithm, the numerical simulations of two realistic targets are finally presented and analyzed.
