摘要
为了评估空中编队的频谱分配效果,改善编队内用频冲突情况,以空中多机编队频谱分配为研究对象,构建了基于干扰三要素的频谱兼容性仿真建模仿真方法,提取了射频发射、接收功能的关键参数并根据工作频带和平台位置关系计算干扰链路损耗,综合考虑主频、谐波、杂散、互调干扰余量,作为频谱分配策略评估的仿真基础。从射频功能抗干扰能力和任务优先级出发,提出了频谱分配策略的评估方法。提出了一种基于智能算法的多平台空中编队用频策略动态优化算法,并在仿真平台上运行测试。仿真结果表明,所提方法能满足多平台空中编队用频动态分配,提升了平均通信速率、信道公平性指标。
In order to evaluate the effect of frequency spectrum allocation in air formation and improve the frequency conflict in formation,a simulation method of spectrum compatibility based on three factors of interference is proposed.The key parameters of radio frequency emission,receiver function are extracted,and the interference loss is calculated according to the working frequency bplatform position relationship.Based on the anti-jamming ability and task priority of radio frequency function,the evaluation method of spectrum allocation strategy is proposed.Finally,an intelligent algorithm for dynamic optimization of multi-platform aerial formation frequency strategy is presented,and the test is run on the simulation platform.The simulation results show that the proposed method can satisfy the dynamic frequency assignment of multi-platform air formation,and improve the average communication rate and channel fairness.
