摘　　要：确立了浮标和海面无线电波传播结构的关系,用浮标作为海上无线通信的中继器,采用标准传播模型(Standard Propagation Model,SPM)对海上浮标通信电波的传输损耗进行仿真,研究频率f、基站天线高度H_(b)和浮标天线高度H_(m)对海面路径损耗的影响。由于浮标的天线长度极其短,极易受海面云雾和水汽的影响,因此提出了一种加入双径反射、云雾衰减和水汽吸收的SPM改进模型,补充了SPM模型未考虑到的参数。用MATLAB仿真,结果显示频率越小,基站天线高度越高,路径损耗越小。研究结果显示,改进的SPM模型更适用于作为基于浮标的海面无线电波传输损耗模型。This paper establishes the relationship between the buoy and the maritime radio wave propagation structure,uses the buoy as a repeater for maritime wireless communication,and uses the Standard Propagation Model(SPM) to simulate the transmission loss of the maritime buoy communication wave.The influence of base station antenna height Hb and buoy antenna height Hm on sea surface path loss is studied.Due to the extremely short antenna length of the buoy,it is highly susceptible to sea clouds and water vapor.Therefore,this paper proposes an improved SPM model with dual-path reflection,cloud attenuation and water vapor absorption,supplementing the parameters not considered by the SPM model.Using MATLAB simulation,the results show that the smaller the frequency and the higher the base station antenna height,the smaller the path loss.The research results show that the improved SPM model is more suitable as a buoy-based sea surface radio wave transmission loss model.
