随着AIS系统在世界范围内的广泛应用，特别是在港口和交通繁忙的沃茨，AIS信息丢失可能与环境条件、障碍物、VHF技术的限制以及AIS网络过载有关，从而降低了AIS信号的成功接收率。选取特定沃茨中八木天线和全向天线同时接收的典型AIS数据，采用网格和AIS数据恢复技术，建立AIS信号覆盖模型，分析AIS基站八木天线和全向天线的信号接收速率，验证八木天线在AIS信号接收速率上的优越性。
: With the wide use of AIS system in the world, especially in ports and the waters with heavy traffic, AIS message loss may be related to environmental conditions, obstacle, limitation of VHF technology and AIS network overload, thereby reducing the AIS signal successful reception rate. This paper selected typical AIS data received by Yagi and Omni antennas at the same time in specific waters, uses grid and AIS data recovery technology, establishes the AIS signal coverage model, analyzes signal reception rate of Yagi antenna and Omni antenna of AIS base station, and verified the superiority of Yagi antenna in AIS signal reception rate.
