AIS信号解调算法研究与实现

AIS Signal Demodulation Algorithm's Research and Implementation

星载AIS分系统为海事管理机构及船舶运营商提供大范围、高效率的船舶状态数据,弥补了岸站AIS系统可视范围受限的缺陷,实现了海上船舶的全球性实时监控。本文简单介绍了星载AIS分系统的实现原理,详细介绍了AIS解调算法。

The satellite-borne AIS subsystem provides maritime authorities and ship operators with a wide range of efficient ship status data,which can make up for the limitation of the visual range of the AIS system at the shore station and realize the global real-time monitoring of the marine vessel.This article briefly introduces the principle of the satellite-borne AIS subsystem.The AIS demodulation algorithm is introduced in detail.
