Embodiment Construction
[0029] The present invention focuses on improving the calculation efficiency of the uncertainty of high-altitude electromagnetic pulse effects. Based on this idea, the following technical solutions are conceived:
[0030] 1. Determine the input parameters and output indicators of the antenna HEMP time-domain coupling response model
[0031] Firstly, according to the antenna structure, select the appropriate metal object electromagnetic scattering calculation tool, create the antenna HEMP coupling response model, and determine the input parameters of the HEMP coupling response model, such as antenna structure size, subdivision size, load, free space relative permittivity and other models Parameters and environmental parameters; and the selection of HEMP excitation field waveforms, such as specific waveforms such as IEC standard waveforms and Bell laboratory waveforms, and corresponding waveform parameters. Determine the output indicators of the coupling response model, such as ...
