摘要:

为提高飞行器编队的低截获性能,提出一种新的低截获概率编队通信方法。将飞行器编队通信视为自适应优化问题,以飞行器节点的辐射功率和拓扑链路作为优化对象,利用混合混沌粒子群算法进行迭代计算,以实现飞行器编队的最优低截获通信。仿真结果表明,混沌粒子群方法在满足可靠通信的前提下,可有效降低编队辐射功率,提高通信拓扑不确定性,改善飞行器编队的低截获能力。

Abstract: In order to improve the low interception performance of aircraft formation,a new method of Low Probability of Intercept(LPI) formation communication is proposed.The communication of aircraft formation is considered as an adaptive optimization problem,and the radiation power and topology link of the aircraft node are taken as the optimization object.The Hybrid Chaotic Particle Swarm Optimization(HCPSO) algorithm is used to carry out iterative calculation to realize the optimal low intercept communication of the aircraft formation.Simulation results show that the chaotic particle swarm optimization can effectively reduce the formation radiation power,improve the communication topology uncertainty and improve the low intercept ability of aircraft formation under the premise of meeting reliable communication.

Key words: Low Probability of Intercept(LPI), formation communication, Hybrid Chaotic Particle Swam Optimization(HCPSO), maximum entropy, objective function
