摘要
Abstract
The configuration of low-earth orbit(LEO)mega-constellations is highly complex,and the presence of numerous satellites with diverse orbital configurations will significantly increase the computational load for co-frequency interference analysis.Traditional serial Monte Carlo sim-ulations require invoking the simplified general perturbations 4(SGP4)orbit model for each sat-ellite at every time step.With the rapid expansion of constellation scales,conventional personal computers are no longer able to meet the computational demands of such tasks.Methods for ana-lyzing co-frequency interference in LEO mega-constellations are investigated in this paper,and a fast computation approach based on a dual-layer parallel strategy is proposed.The proposed meth-od is compared with traditional serial Monte Carlo simulations and a method based on visual air-space partitioning.The simulation results demonstrate that the proposed approach significantly improves computational efficiency while maintaining accuracy comparable to that of conventional methods.It provides scientific basis and support for optimizing design,frequency planning,and coordinating international satellite operators,thereby promoting the rational allocation and utili-zation of space resources worldwide.关键词
