【Abstract】 This paper presents a high-frequency asymptotic numerical approach to solve the problem of radiation analysis for complex antenna systems such as aircraft, ships which are modeled by planar facets. This approach is based on the uniform geometrical theory of diffraction, using the advanced astigmatic beam tracing theory as its ray tracing method. This approach can solve the ray tracing and UTD application problem of any complicated system, so it has the advantages of wide application, fast calculation speed, and can be applied to electrical large systems.更多还原
