The invention discloses a broadband electromagnetic radiation interference characteristic modeling method for a shielding cable network. The method comprises the following steps: 1) obtaining a scattering parameter matrix of a shielding connector and a transmission parameter matrix of a bent shielding cable; 2) constructing an equivalent N port model of the shielding connector by using the scattering parameter matrix, and deducing a transmission parameter matrix of the shielding connector; 3) establishing a multi-conductor transmission line equation reflecting the distribution of interference current on the shielding cable by using the shielding cable transfer impedance; 4) cascading the transmission parameter matrixes of all the bent shielding cables and the shielding connectors to obtain an overall transmission parameter matrix of the shielding cable network; and 5) solving the multi-conductor transmission line equation in combination with the boundary constraint condition to obtain the common-mode interference current of the shielding layer of the shielding cable, and calculating the electric field radiation of the shielding cable network through the dipole array theory. The method is suitable for uniform and non-uniform shielding cables and shielding cable networks of single-core and multi-core wire harness shielding wire types, and has good universality.
