针对海面传输的多径AIS信号，基于衰落算法研究了不同传输模式下接收到的AIS信号的损耗，并分析了不同海况对AIS信号的影响。对海面传输的AIS信号的多径衰落信号进行了数值研究和仿真分析。该研究为利用AIS信号传播延迟测量的多径信号定位过程以及海上工程中可靠的VHF通信链路设计提供参考。此外，本研究成果为在多种多径信号的定位过程中使用AIS信号实测传输时延提供了评估结果，为海洋工程中针对VHF信号的可靠通信链路设计提供了参考。
This paper investigates the losses of AIS signals received in different transmission modes based on a fading algorithm for multipath AIS signals transmitted on the sea surface and analyzes the influence of different sea conditions on AIS signals. A numerical study and simulation analysis of multipath fading signals for AIS signals transmitted on the sea surface are performed. This study provides a reference for the positioning process of several multipath signals using the propagation delay measurement of AIS signals as well as for reliable VHF communication link design in offshore engineering. In addition, the results of this research provide evaluation results for using the measured transmission delay of AIS signals in the positioning process of several multipath signals and provide a reference for reliable communication link design in marine engineering for VHF signals.
