Notice of Removal: A Ray Tracing Based RCS Reduction Method for Complex Cavity Structures

Cavities typically exhibit high Radar Cross Section (RCS) characteristics due to their structural features that allow multiple reflection mechanisms. For stealth platforms, it is crucial to design these cavities in a manner that minimizes electromagnetic backscattering from the structure. This paper presents an approach for optimizing the thickness of radar-absorbing materials using a ray tracing algorithm to reduce the RCS of a cavity resembling an S-type intake. Following this, the optimized cavity is integrated into a simplified unmanned combat aerial vehicle to evaluate the overall reduction in RCS for the platform.
