固定卫星业务中静止卫星网之间干扰计算的极化差别的估计
Estimation of Polarization Discrimination in Calculations of Interference between Geostationary-Satellite Networks in the Fixed-Satellite Service
- 适用范围
- The ITU Radiocommunication Assembly, considering a) that more than one geostationary-satellite network in the fixed-satellite service (FSS) operates in the same frequency band; b) that interference between networks in the FSS contributes to noise in each network; c) that it is necessary to protect a network in the FSS from interference by other such networks; d) that the detailed estimation of mutual interference between satellite networks, due to increased orbit occupancy requires more accurate values of polarization discrimination, resulting from the use of different or identical polarizations by wanted and interfering systems; e) that the use for actual coordination requirements of the values of polarization isolation factors in Appendix 29 to the Radio Regulations, would not provide a precise estimation of polarization discrimination in the calculation of actual interference margins.
