AIS系统在海洋遥感卫星的应用与设计优化

The Design Optimization and Application of AIS on Ocean Remote Sensing Satellite

目前国际和国内已普遍采用星载船舶自动识别系统(Automatic Identification System,AIS)接收系统提升针对全球船只信息的采集和监测能力。本文主要介绍了国内外星载AIS系统发展的主要进展及取得的成果,重点针对目前星载AIS系统存在的近海船只密集区域信号碰撞导致检测概率降低的技术问题,通过建模仿真找到具体原因,给出后续AIS星载载荷针对此问题在设计和应用上的优化建议。本文可作为后续星载AIS系统设计的参考。

At present,the onboard AIS receiving system has been widely used internationally and domestically to improve the capability of global ship information collection and monitoring.This paper mainly introduces the main progress and achievements of the development of the AIS system in the world.Focusing on the technical problem of reducing the detection probability caused by the signal collision in the dense area of offshore ships t,the specific reasons are found through modeling and simulation,and the optimization suggestions for the design and application of the subsequent AIS satellite borne load are given.This paper can be used as a reference for the subsequent design of onboard AIS system.
