Abstract
The aggregate interference from international mobile telecommunications(IMT)base stations on S-band space rendezvous and docking communications is analyzed targeting future sce-narios involving the sharing of spectrum across space,air,and ground.Through simulations,the aggregate interference power from IMT base stations on S-band space rendezvous and docking communications is estimated.Additionally,combined with actual monitoring data,an assess-ment of aggregate interference in the S-band for low earth orbit regions at low latitudes is conduc-ted.The research results show that the interference power from a single IMT base station is pri-marily determined by the antenna gain of both the IMT base station and the target vehicle's ren-dezvous and docking communications antennas at a given relative elevation angle.Furthermore,it is found that reducing the distance between the IMT base station and the target vehicle cannot mitigate the decreasing of interference power caused by the decrease of antenna gain.The aggre-gate interference in the S-band for low earth orbit is mainly influenced by the deployment of IMT base stations.In densely populated areas,the aggregate interference power is relatively high,while in sparsely populated regions such as oceans and deserts,the aggregate interference power is lower.Finally,the strategy is proposed for S-band space rendezvous and docking communica-tions to mitigate aggregate interference from IMT base stations,providing feasible solutions for future spectrum sharing between space operations and IMT.关键词
