复杂环境中海上通信局部通信链路中断预测

Prediction of local communication link interruption in marine communications in complex environments

由于海上环境复杂且易受到日凌现象的影响,通信链路容易中断。为了及时恢复正常通信,提出复杂环境中海上通信局部通信链路中断预测方法。分析复杂环境中海上局部通信链路中断原因,构建基于波浪滑翔器的通信链路中断预测框架,在该框架中计算波浪滑翔器链路中断回波时间,确定中断回波信号所在的位置,从而得到海上通信局部通信链路中断预测结果。由实验结果可知,该方法预测在暴雨环境的1.0~1.3 s、2.0~2.7 s、暴风环境的2.0~2.5 s出现接收信号丢失情况,与实际情况一致,说明该方法的预测结果精准。

Due to the complex marine environment and susceptibility to the effects of solar transits,communication links are prone to interruption.In order to restore normal communication in a timely manner,a prediction method for local communication link interruption in complex marine communication environments is proposed.Analyze the causes of local communication link interruption in complex environments at sea,and construct a communication link interruption prediction framework based on wave gliders.In this framework,calculate the wave glider link interruption echo time,determine the location of the interruption echo signal,and obtain the prediction results of local communication link interruption at sea.It can be seen from the experimental results that the method predicts the loss of received signals in 1.0~1.3 s,2.0~2.7 s of rainstorm environment and 2.0~2.5 s of storm environment,which is consistent with the actual situation,indicating that the prediction results of the method are accurate.
