Analysis And Test Of Radio Interference In Civil Aviation

Civil aviation radio frequency safe, orderly, play a decisive role in air transport, is effective to protect the safety of civil aviation flight, along with the rapid development of our national economy, the increasing of people’s living standards, the development of China’s civil aviation transportation industry is also very rapid, with the improvement of the travel needs of the people, the number of China’s domestic airports and routes and flights are also increasing, in order to ensure the safety of civil aviation radio frequency, orderly use, the author in the practical work, to study the civil aviation radio frequency and spectrum characteristics, interference of the civil aviation radio frequency testing, analysis and research, summary a transmitting station illegally set; intermodulation in-terference radio and television stations have high power transmission; cable TV signal leakage interference; high voltage power Transmission line and the stray interference caused by civil aviation equipment are the main reasons that affect the safety of civil aviation radio frequency:1、the radio frequency spectrum characteristics, modulation mode and other pa-rameters are analyzed, and the causes of the interference of civil aviation radio is ana-lyzed.2、 the research on the civil aviation radio interference test results is analyzed:(1)、 by the radio management department or the civil aviation sector by taking the establishment of civil aviation radio monitoring stations or small stations, the electro-magnetic environment around the airport to monitor the electromagnetic environment in real time;(2)、 Establishment of civil aviation radio monitoring database, the test data in ac-cordance with the frequency, field strength, bandwidth, modulation method, etc., in the presence of interference, can use the monitoring system to monitor the interference source, and monitoring database for comparison, can further the interference source to carry out direction finding, locating work, identify the source of interference, so as to ensure the safety of civil aviation flight, and orderly use, to prevent civil aviation radio interference.
