A modeling method for synthetical scene based on the electromagnetic model

Aiming at the demand of the detection and recognition of the typical scene and the key condition for the radar, a modeling method for synthetical scene based on the electromagnetic model is proposed. Firstly, based on the target group-varying parameters of the targets, including the position and gesture, and the geometry material modeling of targets by the three-dimensional geometry transform method. More, use the electromagnetic calculation method to acquire the narrow-band and wide-band electromagnetic scattering characteristic of the complex scene, including specular reflection, edge diffraction and multi-reflection from the target group are obtained by Physical Optics (PO), Equivalent Edge Currents (EEC) and Shooting-and-Bouncing Ray (SBR) methods. The simulation example analyses the wide-band swept data and the HRRP course feature, and validates the correctness of the modeling method of complex scene.
