Currently, there are many independent and closed "chimney" simulation systems in some range training systems, which is not only a waste of resources but incompatible with other systems well. In view of this situation, the paper focused on using of the testing and training architecture (TENA) that US developed to make improvements. According to the characteristics of TENA's architecture, the paper summarizes the framework to adapt the domestic simulation systems. Finally, the conclusion shows that it can improve the performance of the system using TENA in the domestic simulation system.
