Summary:The invention discloses a time-domain mixing method for fast obtaining antenna parameters. The time-domain mixing method comprises the following steps: firstly, dividing an antenna into a time-domain physical-optics (TDPO) region and a time-domain integration method (TDIE) region and then establishing a TDIE-TDPO mixing equation according to boundary conditions; in the TDIE region, adopting a TDIE equation based on marching-on in-time (MOT), adopting RWG base function dispersion in spaces, and adopting triangular base function dispersion in time; after performing dispersion on the TDIE-TDPO mixing equation, performing test and obtaining a linear matrix equation system in the time and spaces; calculating the linear matrix equation system so as to obtain the induction current of an antenna surface. Through the time-domain mixing method disclosed by the invention, the wide-band frequency information of antenna parameters can be fast obtained, and the time-domain mixing method is especially effective to extract the antenna parameters of ultra wide bands (UWB).
