Analysis For The Antenna Interference Of Multi-vehicular Communication System In Spatial Weather

The electromagnetic interference between vehicular wireless communication devices is a serious problem in EMC design for vehicular communication system all through. To the single vehicle, there has been much research of the EMC problems; but the study of the antenna interference of multiple vehicles is being another new research field. In this paper, a model for interference calculation between wireless communication devices of multiple vehicles in Special Environment, is presented to analysis this interference, which can give the academic sustain to EMC design of multiple vehicles.In the paper, firstly, the basic theory of analysis of electromagnetic interference between wireless devices is introduced; and then by using MOM applied with Spatial Decomposition Technique the antennae coupling, the most important parameter in this model, can be calculated. Then the basic theory of the propagation of electromagnetic wave applicable to analyze electromagnetic interference between wireless devices in special environment is introduced, applied with special scattering of electromagnetic wave, the influence of atmosphere environment to the propagation of electromagnetic wave is analyzed as emphases, and a simple and reasonable model of the propagation of electromagnetic wave based on delaminating structure of atmosphere is established, which is analyzed, and some conclusions are given together with the simulations.At last, electromagnetic compatibility emulation programmer for Vehicular communication System software is developed, which is involving of the influence of landform and physiognomy.
