摘要:

对星载自动识别系统（AIS）所涉及的接收冲突问题及接收概率进行了分析和论证。首先，建立了基于星载AIS系统的观察、分析模型；然后，理论分析了星载AIS接收冲突概率并给出了接收冲突概率公式；最后，对相关理论结果进行了Matlab仿真。

关键词: 星载自动识别系统低轨卫星船舶侦测概率接收冲突概率

Abstract:

The performance is evaluated with respect to ship detection pr obability for a spacebased AIS(Automatic Identification System).First, an obse rvation model for the spacebased AIS system is established.Then,analytical ex pressions for the ship detection probability are developed.Finally,theoretical r esult is simulated by Matlab.

Key words: space-based AIS LEO satellite ship detection probability reception collision probability
