Abstract

Radar Cross Section (RCS) is a physical quantity that quantifies a target’s ability to reflect radar waves in a given direction. Determining it is a major challenge, particularly from a scientific perspective due to the mathematical and numerical techniques required. In the context of operational simulations for radars, the goal of my internship was to design an RCS computation code based on 3D models of targets, that is computationally efficient and robust. This report outlines both the theoretical and numerical aspects of the subject : it aims to detail and justify the choices of modeling and implementation made to meet the computation time constraint, in the specific context of radars. A theoretical and experimental study of errors was conducted, ensuring that the final code provides reasonable solutions for realistic complex targets. Finally, the limitations of our approach have been identified, and several possible improvements are suggested.
