摘要
针对现代电子战随队支援任务中面临的动态频谱对抗与多目标干扰优化难题,提出了一种基于频控阵(FDA)的智能协同干扰任务规划方法.通过建立包含假目标密度、暴露概率和能量消耗的三维效能评估模型,采用非线性频控函数设计动态频谱分配算法,提出分布式协同干扰方法,实现了干扰资源在时-频-空三维度的自适应调度.仿真结果表明,立方频控函数展现出最优的假目标分布特性;频偏增量基准值为60MHz时可实现隐蔽性与干扰密度的最佳平衡;帕累托前沿分析量化揭示了干扰密度提升与暴露概率降低的效能权衡关系;干扰机间距验证确定了空间部署约束规律;能耗对比证实所提方法较传统方案能够有效降低能量消耗.
Aimed at the problems of dynamic spectrum confrontation and multi-target jamming optimization faced in modern electronic warfare(EW)escort support missions,this paper proposes an intelligent cooperative jamming planning method based on frequency diverse array(FDA).Through establishing a three-dimensional ef-fectiveness evaluation model incorporating false target density,exposure probability and energy consumption,non-linear frequency control function is used to design a distributed dynamic spectrum allocation algorithm,achieving the adaptive scheduling of interference resources across time-frequency-space dimensions.Simulation results are demonstrated as below:The cubic frequency control function exhibits optimal false target distribution characteris-tics.When the frequency offset increment baseline value is 60 MHz,the optimal balance between concealment and jamming density can be achieved.Pareto frontier analysis quantitatively reveals the performance trade-off re-lationship between the increase in interference density and the decrease in exposure probability.The verification of the jammer spacing has determined the spatial deployment constraint law.The energy consumption compari-sons confirm that the proposed method significantly reduces energy consumption compared with the conventional schemes.
