Summary:The invention relates to a case radiation emission simulation method and system. The method comprises the following steps: constructing a simplified aperture array model and an aperture case simplified model; taking a PCB in the coupled microstrip line simulation case as a radiation source, setting a voltage source as excitation, and obtaining near-field source data of the coupled microstrip line by adopting a time-domain electromagnetic simulation method; according to the position of a near field source placed in a PCB (printed circuit board) in a case, an electric field monitor probe is arranged at an N-meter method position of a tested case, N-meter method electric field radiation and emission electric field simulation data obtained by a time domain electromagnetic simulation method is compared with standard limit value information, and if a limit value is exceeded, the relative position between a cable and a hole seam and the position of a microstrip antenna are adjusted, and the position of the microstri
