AI Technical Summary
In the existing technology, electromagnetic scattering modeling methods for targets in anisotropic media suffer from low computational efficiency, high resource consumption, and insufficient research, especially lacking effective means in high-frequency modeling.
A high-frequency modeling method combining ray tracing, geometric optics, and physical optics is adopted. The generalized reflection coefficient and transmission coefficient are derived by spectral domain method. Combined with ray tracing technology of type I and type II waves, the ray path is calculated and the scattering field contribution is superimposed to achieve efficient electromagnetic scattering modeling.
It improves computational efficiency, reduces computational resource consumption, and reveals the complex propagation process of Type I and Type II waves in anisotropic media, providing a low-cost technical means for radar target detection and identification.
