| 摘 要： | 大容量浮标通信由于浮标体摇摆和多径的影响,其电波传播的可靠度通常不理想,而忽略工作频率的选择和天线工作形式的研究是浮标通信这种海面微波移动通信传输设计可靠度不高的一个重要原因。针对采用何种工作频段和天线工作方式有利于浮标通信电波传输,通过对几组不同工作频率在海面多径条件下相关通信距离的归一化合成场强理论特性进行仿真和测试,提出了采用1～2 GHz波段和垂直极化的浮标端全向天线和岸端定向天线工作方式更有利于浮标通信。

| Abstract: | The electric wave transmitting reliability of large capacity buoy communication is usually not ideal due to buoyage shake and sea surface multipath.And neglecting the choice of operation frequency and antenna work form causes low reliability of large capacity sea-surface microwave mobile communication.To facilitate electric wave propagation for buoy communication,simulations and test for different working frequencies were performed to study the theoretical characteristics of synthesize field density of communication distance in sea surface multi-path fading conditions.And it is proposed that 1～2GHz wave band,omni-directional antenna with vertical polarization,and directional antenna in the sea coast are suitable for buoy communication. |

| Keywords: | polarization type multi-path fading field density operation frequency |
