Problems solved by technology

With the development of weapon system seeker technology and target simulator technology, target simulation has developed from point source targets to area targets and body targets. A large amount of data will be generated in the process of calculating the target characteristics of area targets and body targets. The data transmission rate of the memory network can no longer meet this requirement. At the same time, the data generated by solving the target characteristics is only needed by the target simulator. If the target characteristic data is transmitted through the main network of the simulation system, it will cause network congestion and reduce the network communication efficiency of the simulation system. , it will cause problems such as simulation timeout
