| Abstract: |
| Space-based AIS(Automatic Identification System) signal reconnaissance system c
an intercept AIS signals of vessels around thousands of sea miles to form AIS si
tuation information of national adjacent seas as well as global sea area. In th
is paper,a particular scheme of dual-channel space-based AIS receiver is presen
ted after analysing the related research results around the world, and the key p
arameters are demonstrated and compared. The results provide theoretical referen
ce for developing universal and applicable space-based AIS receiver system. |
