摘要

编队作战时,电子设备间的电磁辐射干扰严重制约信息化作战效能.合理管控电磁频谱,优化频谱资源的使用意义重大.传统的随机优化算法存在优化速率慢的问题.该文基于复杂网络理论建立了编队电磁兼容网络模型;以综合网络收益和成本的网络效能值最大为优化目标,提出一种基于复杂网络节点重要度的电磁兼容网络规则优化算法.理论分析与仿真结果表明:所提出的规则优化算法与现常用的随机优化算法相比,网络效能优化速率提升了13.35％,优化性能更佳,可望为实际应用提供一定理论借鉴.%It is of great importance to control the electromagnetic spectrum and optimize the use of spectrum resource because electromagnetic interferences between different devices may cause vicious influence while combating in formation.Traditional random algorithms for the optimization of spectrum use suffer from painfully slow optimization speed.In this paper,a model of ElectroMagnetic Compatibility (EMC) network in the case of formation is developed based on the complex network theory.By maximizing the network performance in terms of both benefit and cost,this paper proposes a rule optimization algorithm of EMC network considering node importance.Both theory analysis and simulation results show that optimization speed is increased by 13.35％ and the optimization performance is enhanced.The proposed algorithm not only accelerates the optimization for the use of spectrum resource but also provides a theoretical reference for practical applications.
