Abstract
This study examines the Radar Cross Section (RCS) of a cylindrical target, with a focus on the effects of pulsed signal transmission and target motion. Traditional RCS analyses often rely on continuous wave (CW) excitation and assume stationary targets, which may not accurately capture the dynamics encountered in practical radar scenarios. The RCS of the cylindrical target is computed under pulsed signal excitation and compared with the results obtained under CW conditions. To assess the influence of geometry, the model is extended to a disk-shaped target by reducing the height of the cylinder. The impact of target motion is incorporated using Doppler-based modeling, revealing how the interaction between signal characteristics and target dynamics affects the RCS. These results provide valuable insights into improving radar detection accuracy and refining RCS reduction techniques. Key strategies such as scattering control, absorption, and the use of radar-absorbing materials (RAMs) and metasurfaces must account for these dynamic conditions to achieve optimal performance. Although this investigation focuses on cylindrical structures, the methodology presented can be applied to other simple geometries, enhancing its relevance to practical RCS management. Future extensions may include modeling targets with more complex structures and incorporating advanced source modeling techniques, such as different types of pulsed and modulated signals, to further approximate real-world radar environments.
