摘　　要：天基AIS信号侦察系统可获取上千海里内船舶的AIS信号,形成国家周边海域乃至全球海域的AIS态势信息。通过分析国内外相关研究成果,提出独特的天基双通道AIS接收系统方案,并对关键参数进行论证比较,为研制通用性和平台适装性好的天基AIS侦收系统提供理论参考。Space-based AIS（Automatic Identification System） signal reconnaissance system can intercept AIS sig- nals of vessels around thousands of sea miles to form AIS situation information of national adjacent seas as well as global sea area. In this paper, a particular scheme of dual - channel space-based AIS receiver is presented after analysing the related research results around the world, and the key pmarr^ters are demorr^tmted and compared. The results provide theoretical reference for developing universal and applicable space-based AIS receiver system.
