Embodiment 1
[0109] This embodiment has carried out the simulation of the electromagnetic scattering characteristics of a plurality of metal targets, and the simulation is realized on a personal computer with a main frequency of 2.83GHz and a memory of 3.5GB. Three cubes with a side length of 0.3 meters have center coordinates respectively (0,0, 0), (0,0,1.6), (1.2,0,0), the equivalent surface is a spherical surface with a radius of 0.4 meters. Using modulated Gaussian plane wave excitation, the maximum frequency is set to 300MHz, the center frequency is 150MHz, and the incident direction is θ, The subdivision size of the metal cube is 0.1m, and the equivalent surface is divided into two types of meshes: triangle and ring, among which the subdivision size of the triangle is 0.12m, and the busbar is divided into 16 segments on average, using 3 Fourier modes , calculated up to order 50. In order to verify the correctness and efficiency of the program, the results of this patent are compare...
