[Abstract]:With the rapid development of vehicle information, more and more vehicle electronic information equipment is widely used. The diversification and complexity of vehicle electronic information equipment can significantly improve the performance of vehicle on the one hand, and on the other hand, it also faces the threat of complex electromagnetic environment. The electromagnetic interference (EMI) problem of the onboard antenna system on the same platform is becoming more and more serious due to the different kinds of antennas, the number of antennas, the working frequency, the installation mode, etc. Therefore, it is of great theoretical and practical value to study the electromagnetic compatibility of antenna system on board. Based on the research project of "electromagnetic compatibility simulation analysis of XX combat vehicle multi-function RF sensor", based on the background of electromagnetic compatibility analysis of a certain type of vehicle, a vehicle electromagnetic model is established with the help of professional software. And use CST simulation software to analyze the electromagnetic compatibility of the antenna system, the main work is as follows: 1. The electromagnetic compatibility (EMC) of a vehicle antenna system is preliminarily discussed in view of the actual geometry, size, material characteristics and operating environment of a certain type of vehicle. Combined with the specific working object to be explored, this paper briefly discusses the vehicle electromagnetic compatibility analysis method. 2. 2. By using CAD software with graphic processing ability and considering the characteristics of the carbody which affects the electromagnetic compatibility of the antenna system on board, the full-size real carbody electromagnetic model .3of a certain type of vehicle is established. Based on the real vehicle electromagnetic model, the electromagnetic compatibility analysis of the antenna system is carried out. The antenna pattern and the effect of antenna spacing on antenna coupling are simulated and analyzed, and the layout scheme of two kinds of antenna system is given. This paper briefly introduces the external radiation source and analyzes the influence of the external radiation source on the vehicle multi-antenna system.
