AbstractIn recent years,due to the rapid growth of air traffic controlbusiness and the increasing number of control sectors,theVHF equipment and frequency of ground to air communications are increasing. Theelectromagnetic environment is deteriorating,and manyinter-system interference are gradually emerging. This paper puts forward somesuggestions for the construction and maintenance of VHF stations through asurvey of intermodulation interference.
