摘要
针对大气波导环境下舰载超视距通信过程中通信电磁盲区的存在会造成通信信号的中断,使处于盲区内的目标无法接收信号的问题。利用射线追踪理论研究电磁波在波导环境下的传播特征,仿真分析了通信系统不同发射参数变化对电磁盲区分布的影响。仿真结果表明:对大气波导顶端通信电磁盲区影响较大的是发射天线高度和发射仰角的变化,而减小发射仰角对第一个跳跃点的跳跃盲区影响较大。
In the process of shipboard 0TH communication atmospheric ducting environment, the existence communications electromagnetic blackout can cause communication interruption of signals, and the target within the blackout cannot receive signals. We researched electromagnetic wave propagation characteristics in the ducting environment that make the use of ray tracing theory, simulated and analyzed the effects of the varies different parameters of communications systems to electromagnetic blind distribution. According to the simulation results, the electromagnetic blind on top of the atmosphere ducting that has more serious effects is the change of the height of the transmitting antenna and transmitter elevation, and the decrease of transmitter elevation has greater impact on hopping blind of the first jump point.
