| Abstract: |
| To improve the ground maneuvering target tracking accuracy, a variable struc
ture interaction multiple model(VS-IMM) target tracking algorithm based on t
he geographic information constraints is proposed and evaluated. Firstly, the ge
ographic information restrictions are included in both target observation and dyn
amic models to obtain the target state estimates. Then, the time-varying target
maneuvering model set can be derived from the curvilinear model of the filter.
Finally, the VS-IMM algorithm using geographic information constraints can be ap
plied for the ground maneuvering target tracking more practically. Simulation re
sults show that the proposed algorithm has a better performance than the existing IMM
maneuvering target tracking algorithm for the airport maneuvering targets. |
