INTRODUCTION
This chapter describes a general methodology that can be used in the analysis of interference between similar and dissimilar radio systems and provides the procedures for calculating the distance and frequency separation required to prevent harmful interference to systems used by aviation for communication and (radio) navigation purposes.
For a more detailed analysis, taking into account the aeronautical compatibility requirements, the method as described in ITU-R Recommendation SM.337 on "Frequency and distance separations" may be used in some cases. Also relevant are the provisions of ITU-R Recommendation SM.1535 on "The protection of safety services from unwanted emissions".
