摘要：
The space-based AIS (Automatic Identification System) is a recently introduced system for traffic monitoring and safety at sea. When both Class A and Class B transmitters are located in the water area, the Class B signals are likely to interfere with the desired Class A signals. This is an important issue for satellite-based AIS. The objective of this paper is to show how useful stochastic models of AIS signal reception can be constructed to assist in the optimization of space-based AIS receiver systems. Based on the probability theory, this paper proposed the mathematical reception model of space-based AIS signal. In this stochastic model we considered the existence of Class B signals. From the simulation we obtained the relationship between the detection probability and the ships number. And then we analyzed the results and proposed the improvement method of the model. The result of the simulation is proved to be correct and the proposed method provides the relevant theoretical basis for the implementation of space-based AIS in China.
