However, there is no relevant research on this issue. In this paper, the full-scale electromagnetic simulation model of the shared tower is established in FEKO software. Then, based on the multi-layer fast multipole theory and the generalized S-parameter theory, the far-field radiation pattern of the antenna and the expression of the coupling degree of the multiple antennas are given. Based on the above research, the change rules of the far-field radiation pattern and the coupling characteristics of the multiple antennas on the shared tower are calculated respectively. The results show that the radiation pattern and coupling degree of multiple antennas are related to harmonics, antenna spacing, antenna frequency and surrounding scatterers. Based on the calculation results, the suggestion of 1.5m protection spacing is given. The research results of this paper can provide reference for EMC analysis and multi antenna layout optimization of the shared tower.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122968960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excessive grounding current will lead to poor grounding reflux of EMU, which will bring security risks to the normal operation of EMU. Therefore, in order to study and predict the size and distribution of the EMU grounding current, analyze the EMU grounding performance and electromagnetic compatibility of the grounding system, it is of great significance to establish the EMU grounding current simulation model. In this paper, the grounding system of standard emu was briefly introduced, and according to the structure and parameters of the grounding system, the equivalent circuit model of grounding system of the standard EMU was established by using the simulation software. The distribution characteristics and rules of the grounding current at the axle end of EMU under the independent grounding and mixed grounding were analyzed. The conclusions are working grounding current at the axle end is greater than the protective grounding current when the independent grounding is adopted. The mix grounding is beneficial to the shunting of the working grounding current so that the working grounding current at the axle end is reduced.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132224629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern warfare is no longer a single force or single equipment operation, integrated joint operation has gradually become the development trend of modern high-tech war. The EME adaptability of weapons and equipments is directly related to the initiative in the war. Aiming at the urgent requirement to improve the adaptability and combat capability of weapons and equipments in complex EME, by means of electromagnetic simulation, the operational style and operational process of typical avionics are analyzed, the composition and characteristic elements of battlefield EME are studied, the scene model of battlefield dynamic EME are built. With the combat scenario and typical mission profile, communication link and interference link are taken as the evaluation object, and the real-time EME adaptability of weapons and equipments is analyzed by electromagnetic hybrid algorithm. The electromagnetic simulation is extended from platform level to scene level, and the electromagnetic effect of system cooperative operation is incorporated into the EMC design process.

For this design, the lightweight bulletproof material is also used as the dielectric substrate of composite material structure. And six layers of resistance film is inserted in the seven layers of bulletproof material. The conductivity of each layer of resistance film is 55 S/m. Bulletproof material uses PE laminated. The measured results show that the integrated composite material has an absorption rate of more than 90% in the 6.88GHz~30.58GHz, which also can effectively protect the 53-type 7.62mm ordinary steel core bullet. The thickness of stealth bulletproof integrated composite material is 17.5mm, which achieved the light and thin character. The stealth bulletproof integrated composite material is designed through the combination of the absorbing structure and the bulletproof material. The implement method of stealth bulletproof material is no longer a simple functional overlay, but an integrated fusion design of structure and function. It solves the shortage of traditional stealth bulletproof materials. This design method has great significance for improving the combat capability of new functional vehicles.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133069030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
