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.
In order to solve the problems of multi-user time slot conflict and delay in signal transmission when receiving AIS signal from satellite, a comparative analysis of the correct detection rate of satellite receiver ship is given for the new AIS scheme. At the same time, Class hybrid distribution and the correct detection rate of Class A ships in different sea areas.The new scheme can improve the detection rate of satellite receivers.
