Simulation and study on fusion precision influenced by data link time delay

GUAN Cheng-bin1*,WANG Guo-hong1,LI Shi-zhong1,WANG Na 1,2(1.Inst of Inf Fusion Tech,Nav Aeronaut & Astronaut Univ,Yantai 264001,China; 2.Elem 93 Unit 92941 of PLA,Huludao 125001,China)  
To make clear the influence of data link time delay in the fusion of radar track and data link track,the track fusion precision of different data link time is compared and analyzed with and without time delay modification.The results show that if the time delay is short,its influence on fusion precision is little,and the effect of time delay modification is not obvious either.If the data link time delay is longer than 500 ms,the fusion precision will be increased obviously.And the longer data link time delay is,the more obviously the fusion precision is increased.
