为解决卫星接收AIS信号时存在多用户时隙冲突、信号传输过程中时延等问题，针对新的AIS方案，给出卫星接收机船舶正确检测率比较分析结果，同时，给出A类和B类混合分布以及不同海域下A类船舶的正确检测率. 该新方案可以提高卫星接收机的船舶检测率.
Abstract
Satellitebased AIS receiver is developed to achieve global maritime surveillance via satellite receiver. In order to solve problems of delay and slot collision in satellitebased AIS receiver, this paper gives experimental results of correct detection rate for an improved scheme of AIS. Meamwhile, the correct detection rates of Class A in various modes for improved scheme are also given. The proposed scheme can improve the correct detection rate of the satellitebased AIS receiver.
