干扰下岸舰通信畅通区可视化仿真研究
|
摘要
岸舰通信作为舰艇编队与陆基指挥所通信的重要手段,保持通信畅通是十分关键的。针对电离层随机变化影响通信畅通区仿真的问题,以战时通信使用频率最高的一跳反射为例,进行了可视化仿真。首先基于工程中常见的电离层模型建立了反射高度的计算模型,提出了有无干扰条件下岸舰通信畅通区计算模型、数据采样和可视化方法,并且基于仿真平台进行了仿真。从实现效果来看,能够满足仿真要求,并且更加直观形象地展现通信状态,为装备的部署和工作参数选择提供方法。
The shore-ship communication is an important means of communication between ship formation and land-based command posts, thus it is crucial to keep communication smooth. To solve the problem that the random variation of ionosphere affects the simulation of smooth communication zone, we took the one-hop reflection with the highest frequency of wartime communication as an example and carried out visual simulation. Firstly, based on the ionospheric model commonly used in engineering, the calculation model of reflection height was established. The calculation model, data sampling and visualization method of the smooth communication area of shore-ship communication with and without interference were proposed, and the simulation was carried out based on the simulation platform. The realization effect showed that:It can meet the simulation requirements, and display the communication status more intuitively, which provides a method for equipment deployment and work parameter selection.
