摘要
针对电子试验场内存在试验频次较高、频率冲突严重和空间布局有限等问题,基于三维地理信息及设备模型,建立基于Unreal Engine 4(UE4)平台的综合电子试验场。采用计算电磁学方法和远场分析技术,通过时域有限差分(Finte Difference Time-Domain,FDTD)法、一致性绕射理论(Uniform Theory of Diffraction,UTD)、射线跟踪法等算法优化调整场内设备时、空、频参数。提出了一种改进的FDTD网格划分方法,完成场区设备电磁干扰分析。仿真结果表明,提出的仿真系统有一定的有效性和可靠性。
For the problems of high test frequency,severe frequency conflicts,and limited spatial layout in the electronic testing field,a comprehensive electronic testing field based on the Unreal Engine 4(UE4)platform is established based on the three-dimensional geographic information and the equipment model.By using computational electromagnetic methods and far-field analysis techniques,the time,space,and frequency parameters of on-site equipment are optimized and adjusted through algorithms such as Finite Difference Time-Domain(FDTD)method,Uniform Theory of Diffraction(UTD)consistent diffraction theory,and ray tracing method.And an improved FDTD grid generation method has been developed to complete the electromagnetic interference analysis of the equipment in field.The simulation results indicate that the proposed simulation system has certain effectiveness and reliability.
