直扩通信抗干扰动态博弈模型研究

摘要
通信对抗中通信方与干扰方对频谱资源抢夺的动态竞争过程难以分析,提出一种基于Lotka-Volterra模型的干扰与通信抗干扰动态博弈建模方法,并将其应用于干扰环境下的直接序列扩频抗干扰通信。根据对抗双方的行为特点,从理论上分析了双方实际有效占用频谱资源数量的情况,证明了双方占用频谱数量的平衡点的存在,并对干扰方干扰概率进行了推导。仿真结果验证了该模型的合理性和应用于直扩通信的可行性,并分析了采用直扩通信时系统的抗干扰性能。
In military communication,it is difficult to analyze the dynamic competition process of occupying spectrum resources by communication users and jammers.In order to solve this problem,this paper proposes a dynamic game modeling method based on LotkaVolterra model for jamming and communication anti-jamming,which is applied to the direct sequence spread spectrum( DSSS)communication anti-jamming environment.According to the behavior characteristics of the two parties,the actual effective occupancy of the number of spectrum resources is analyzed theoretically,the existence of the equilibrium point is proved,and the jamming probability of the jammers is deduced.The simulation results show that this model is rational and feasible in DSSS communication.The anti-jamming performance of system in DSSS communication is analyzed.
