Civil Airport Radio Electromagnetic Environment Test And Interference Analysis

Information era of globalization in the 21 st century, Radio technology should be widely and widely used, the human spirit and the material and cultural life has played an irreplaceable influence. At the same time, China's civil aviation industry under the background of normalization development also got unprecedented development. However, as in all walks of life more and more demand for radio frequency resources, set up the data density is becoming more and more big, the radio equipment and its application in different extent, affects the safety of civil aviation business and. All kinds of electromagnetic interference caused by all kinds of damage and interference of civil aviation special radio frequencies events emerge in endlessly. As a result, the new airport electromagnetic environmental protection must be considered in site selection and electromagnetic environment test before, in order to avoid in the airport after the completion of other emission equipment to civil aviation special radio frequencies, caused heavy losses. At the same time, should be formulated and the monitoring network layout of the overall situation in matters relating to the urban planning, construction cover whole city airspace, reaction timely, accurate positioning, monitoring and efficient radio monitoring network, the implementation of the total business of radio spectrum, full time, all-round monitoring.The paper first expounds the related radio, radio spectrum management and radio monitoring knowledge, and the electromagnetic environment requirements of all kinds of civil aviation ground stations. And then describes the airport radio electromagnetic environment the composition of test system, test method and data processing method. Combined with the status quo of the current civil aviation radio interference, this paper discusses the different industries of aviation beacon (station) interference principle and basic types. Analyzed the FM radio interference area calculation model, and use Mat lab to the simulation calculation model. Finally with the instance of the United States civil aviation radio interference monitoring network, the development of Chinese civil aviation radio is compatible for the future were discussed.
