Abstract
In this letter, the divergence factor (DF) correction is implemented in the shooting and bouncing ray method (SBR) to improve the accuracy of radar cross section (RCS) simulations of triangular meshed curved targets. Based on the surface fitting technique and differential geometry, the curvature information of the triangular surface mesh is reconstructed and the resulting DF of the wavefront is taken into account. For the diverging ray tube, a supersampling ray tracing method is proposed to address the ray-mesh resolution mismatch. This enables us to accurately find the illuminated region on the target surface. Meanwhile, the divergence coefficient is introduced to correct the incident field. The monostatic RCSs of some targets with curved structures are simulated. The simulation results validate the effectiveness of DF correction for SBR in improving the accuracy of RCS simulations of curved targets.
