Abstract:
The present and future development of the FM sound-broadcasting networks in our country can lead to unacceptable interferences with the navigation and communication radio equipment of aeronautical services. Two kinds of interferences - these resulting from intermodulation products caused by different radio transmitters operating on common antenna tower and these produced when there is a possibility for the aircraft radio receivers input stages to begin operating in non-linear conditions - are especially dangerous and are hard to predict. In both cases the vertical plane radiation pattern of the FM transmitting antennas have substantially great influence. The present article gives criteria for more accurate determination of the area of these two kinds of interferences. The criteria will be used to specе the methods for calculation- the compatibility between FM sound-broadcasting radio stations and the radio equipment of the aircraft services. The methods are recommended by the International.Telecommunication Union /ITU/ and are available in the document 12/1005E, 17 Aug., 1993.
