Antenna pattern visualization method suitable for post-processing of moment method

The invention discloses an antenna pattern visualization method suitable for post-processing of a moment method, and the method comprises the following steps: S1 building an antenna model, and appointing the excitation of an antenna; S2 determining a system matrix and a right side vector required for calculation by the moment method; S3 establishing a spherical angle two-dimensional grid; S4 performing post-processing by using a moment method to obtain far-field directivity data of an antenna vertical polarization direction and horizontal polarization direction synthesis total field of an angle on a vertex of the grid, and recording the far-field directivity data as an enough directivity data list; and S5 performing visualization processing on the antenna directivity data. According to the invention, the matching of the display size of an antenna pattern and the display size of a platform and a model under different application occasions can be met, and geometric measurement of a lobe pattern of the antenna i
