摘　　要：针对机载AIS由于时隙冲突导致的监视性能下降的问题,提出通过分区域接收提高检测概率的方法。通过分析AIS系统的接入过程,深入研究影响系统监视性能的因素,利用MATLAB,基于SOTDMA协议构建全新结构下的机载AIS系统的仿真模型。仿真结果确定了时隙冲突、系统容量和负载之间的关系,表明分区域接收能有效提高检测概率,从而为工程应用提供了有益的参考。Aiming at the problem of monitoring performance degradation by the slot collision on airborne AIS, a muhi-region receiving method in the case of high load to improve the probability of detection of the ships is proposed. The access process of AIS system is analyzed, along with the factors affecting the sys- tem monitoring performance. The simulation model of airborne AIS system, which has a brand new struc- ture based on SOTDMA protocol, is constructed through MATLAB. The performance of airborne AIS is determined and the effect of multi-region receiving method on the detection probability is obtained.
