海上舰艇编队作战中，通信畅通是战争胜利的可靠保证，但受限于硬件条件和功率限制，不能无限增加通信链路，通信网络一旦受到敌方靶向干扰，很容易造成通信中断，影响战场态势。通过对目前常用的几种通信组网模式的研究，提出一种适时中继的通信模型。该组网模式在不改变原通信指挥关系的情况下，较好地解决了低信噪比条件下的编队协同通信问题，一定程度上实现了通信抗干扰。通过仿真分析，验证了该方法较星型连接在低信噪比条件下的信道容量阈值有2dB的提升，系统中断概率也进一步降低。
Smooth communication is a reliable guarantee for the victory of naval fleet battle,limited by hardware conditions and system power,communication links cannot be increased indefinitely，once the communication network is disturbed by enemy targets,it is easy to cause communication interruption and affect the battlefield situation.Based on the research on several commonly used communication networking modes,this paper proposes a timely relay communication model,this networking mode realizes communication anti-interference to acertain extent without changing the original communication command relationship,and better solves the problem of formation cooperative communication under the condition of low signal-to-noise ratio.And through simulation analysis, it is verified that compared with star connection, the channel capacity threshold of this method is improved by 2 dB under the condition of low SNR, and the system interruption probability is further reduced.
