title = "Parametric modeling method of scattering centers for complex target geometric models based on geometric modeling tools",
abstract = "To address the need for rapid modeling of electromagnetic scattering characteristics of complex targets, this paper proposes a geometric feature extraction and scattering center parametric modeling method based on Open CASCADE Technology (OCCT). First, the OCCT library is used to parse the target geometric model (in STEP/IGES format) to extract key geometric parameters such as vertices, edges, and surfaces. Then, combining Geometrical Theory of Diffraction (GTD) and Physical Optics (PO), a mapping relationship between geometric features and scattering centers is established. Finally, the scattering center model of the target is parametrically modeled. This method can effectively reduce computational complexity and provides an efficient tool for radar target identification and Radar Cross-Section (RCS) estimation.",
