【Abstract】 The aperture integration-surface integration(AI-SI) method is a common numerical simulation method for the far-fields of the antenna-radome system.Aiming at the low calculation efficiency problem of the electrical large size antennaradome system,a parallel AI-SI algorithm based on decomposed equivalent source region is presented.An algorithm program is developed and tested in the message passing interface(MPI) environment on a cluster system,and the radiation characteristic of the antenna-radome system is calculated.The simulation results show that the proposed parallel algorithm has higher efficiency and precision.更多还原
