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.

Description

technical field

[0001] The invention belongs to the application category of electromagnetic calculation of electrically large-scale targets, and especially designs an electrically large-size carrier partition calculation method oriented to moment method calculation, which is suitable for simulation calculation of electromagnetic compatibility problems of electrically large-scale systems. Background technique

[0002] For modern mobile communication platforms, such as vehicle-mounted platforms, ship-borne platforms, and airborne platforms, due to their large overall structure, various and complex uploaded equipment, and close frequency bands, the mutual interference is very serious.

[0003] Because the electromagnetic compatibility problem of this kind of system is relatively severe, it is necessary to carry out detailed electromagnetic compatibility simulation on the system when designing the system to obtain the electromagnetic compatibility characteristics of the system, a...
