Analytical modeling of LRCS for multiple scattering of Lambertian dihedral angle
Year: 2026
Type: article
Abstract: Laser radar cross section (LRCS) calculation suffers from errors due to unmodeled multiple scattering. We derive analytical LRCS solutions for 1st- to 4th-order scattering of Lambertian dihedral angles using the BRDF and the light transport equation. We analyze scattering order effects and propose a practical threshold selection criterion, improving calculation accuracy and efficiency for lidar simulations.
