Investigation on wave scattering characteristics of triangular prism targets and their composite scattering with rough surface

To study the electromagnetic echo characteristics of the triangular prism targets and their composite scattering with rough surface, the finite difference calculation model of the composite electromagnetic scattering of rough ground surface and buried triangular prism targets is constructed. The echo data of the triangular prism target in the air with different parameters are obtained, and the influence of different vertex angles and different placement angles on the echo characteristics of the triangular prism target is analyzed. On this basis, the influence of rough surface on the echo characteristics of triangular prism targets with different vertex angles or different placement angles in composite scattering is calculated and analyzed.
