The Electromagnetic Environment Testing And Evaluating Of Tianjin Airport Radio Station

Radio communication technology, as the last century emerging technology, along with the necessary of national economy and the progress of science and technology is rapidly developing and become more and more widely used. With the development of human science and technology, the technical application of the Technology is becoming much more widely. Radio communication has been a rapid development in the context of the high-tech information age. Meanwhile, China’s civil aviation also gradually rise to vigorous development in the background of Reform and opening up. from the founding of the to2009, China’s civil aviation has opened more than300regular flight airport, with1532regular flight routes, more than400foreign routes. In the world of civil aviation, China’s civil aviation has become the world’s second largest aviation transport system. However, some operation chamber of commerce recklessly abuse radio communication technology, the total of many kinds of radio communication station increases sharply. Radio products and technology applications to some extent has an impact on civil aviation operations and safety. A variety of electromagnetic interference has been formed electromagnetic environment which can not be ignored, resulting in the frequent occurrence of hazards and interference with civil aviation radio frequency. Therefore, ensuring the safe use of civil aviation special radio frequency, real-time effective monitoring of the electromagnetic environment, using technology to maintain air frequency resources, timely discover and eliminate interference hazard has attached great importance to the issue for civil aviation system these years. It is also the base of this article.Thesis elaborated electromagnetic theory and knowledge of the radio waves and radio spectrum management, and analysed two radio monitoring and direction finding systems, Then launched a research of numerical simulation and test methods on the electromagnetic environmental and electromagnetic interference by which Civil Aviation Airport wireless radio is faced. The main work and new results of the thesis are as follows:1.Established Airport numerical simulation model of Radio Monitoring Center of Tianjin Binhai International Airport and launched numerical simulation study of the civil airports electromagnetic environment by wireless insite simulation model.2.Analyzed the impact of the presence of electromagnetic interference of the civil aviation system and the impact of the electromagnetic environment interfere with aircraft navigation and communication. Raised airport radio station electromagnetic environmental assessment method and protection programs3.Proposed Tianjin Binhai International Airport electromagnetic environment testing program and some ideas about avoiding interference.The research content in order to show some guidance to the examination and approval frequency for stations, also, for the station to put forward the quantitative indicators. The purpose of the thesis is to provide a new direction for the protection of the safety of civil aviation and radio interference problem.
