With the rapid and continuous growth of civil aviation flight volume in China,the air traffic operation of airports and airspace systems is under great pressure,and the conflicts between air traffic flow and air traffic control support capacity and airspace capacity is becoming prominent.Therefore,how to effectively improve the utilization rate of civil aviation frequency resources within the limited frequency resources attracts much attention and emphasis of international civil aviation industry at present.The reuse spacing of ground frequency,tower frequency,approaching frequency and regional frequency between airports is analyzed,and a mathematical model is established based on the existed technical specifications of civil aviation industry,which gives the calculation and analysis method of frequency reuse spacing between ground and air communications in practical operation through specific quantitative calculation,so as to solve the practical operation problem due to the co-frequency interference caused by cross-region frequency reuse.
