Moment method calculation-oriented calculation method for electrically large carrier divisions

Abstract

The invention belongs to the application field of electromagnetic calculation of electrically large objects, in particular to a moment method calculation-oriented calculation method for electrically large carrier divisions, which is applicable to the simulation calculation of the electromagnetic compatibility problem of the electrically large system. According to the method, practical carrier models are simplified according to the practical equipment layout on a communication platform, and the overall shape and size of the models are kept to the maximum extent through a multi-level model simplification algorithm and on the basis of meeting the practical calculation requirement; and the models are simplified according to the radio wave propagation theory and by taking the local factors of the models related to the practical coupling degree among antennas into account, for example, the influence of a receiving antenna and a transmitting antenna on the local factors of the surface between the models is taken into account, so that the simulation accuracy can be met as far as possible and the double requirements of the calculation time and the calculation accuracy can be met.
