Reference FSS Earth-Station Radiation Patterns for Use in Interference Assessment Involving Non-GSO Satellites in Frequency Bands between 10.7 GHz and 30 GHz
The Recommendation considering that peak envelope antenna reference patterns are necessary for interference calculations involving a non-mobile receiver and a single non-mobile interference source to ensure that the worst case is covered, and that in the FSS such circumstances predominated in the past; that in circumstances where there are multiple interfering sources or receivers whose positions vary substantially with time, the level of interference received inevitably depends on the troughs as well as the peaks in the antenna side lobe gain pattern of the victim or source of interference, respectively, and that the occurrence of such circumstances is rapidly increasing in theFSS.
