摘　　要：船载自动识别系统(AIS)的出现,保证了船舶的通航安全,改善了船舶的通航环境,作为一种船舶监控系统,AIS在内河中通信的可靠性直接决定了其应用前景。针对AIS在我国内河航行中的应用越来越广泛的现状,通过奥村模型的分析方法,计算无线电在不同路径下的传播损耗,采用Matlab对该模型进行仿真,研究了不同环境下AIS基站的监测范围,为改善内河AIS通信的可靠性提供了依据。The appearance of the AIS is a milestone in process of the development of the communication in water area environment,which extremely promoted the safety of navigation and improved the environment of the navigation for shipping.With the development of shipping industry,AIS is becoming more and more extensive in applying for the domestic navigation.As a vessel monitoring system,AIS is in high reliability and its reliability determines its application.According to the analysis of the Okumura-Hata Model,the loss of the radio when it transmits in different path could be calculated.This model was simulated with Matlab and the monitoring range of the different AIS sites was investigated,which provided the basic information for improvement of the stability of the inland AIS.
