摘要

摘要: 针对电大复杂多层介质结构目标电磁散射特性分析与应用对计算资源和效率的需求,提出了基于传输线理论的等效面模型,推导了相应的相位修正算法,实现对此类目标散射特性的快速准确预估.等效面模型将多层介质平板结构等效为平面,基于传输线理论,采用电路分析中常用的网络分析方法计算该平面的反射系数与透射系数,并通过引入多层介质结构厚度、入射和观测方向等信息实现对反射系数与透射系数的相位修正.仿真结果验证了该文方法的正确性和高效性.

Abstract: The Equivalent Plane Model (EPM) and Phase Correction Algorithm (PCA) that are based on Transmission Line Theory (TLT) are proposed to satisfy the resource and efficiency requirements of ElectroMagnetic (EM) scattering analysis of large and complex multilayered dielectric targets. The proposed method accurately predicts the EM scattering characteristics of reference targets. To simplify the analysis, the multilayered dielectric slab structure is considered planar. On the basis of the TLT, the reflection and transmission coefficients of the plane are determined by using network analysis methods typically adopted in circuit analysis. Moreover, the reflection and transmission phases are corrected by considering the thickness of the multilayered dielectric slab and the direction of incidence and observation. Simulation results verify the applicability of the proposed method.
