Study On Distributed Interactive Simulation And Application In Data Fusion

The Distributed Interactive Simulation (DIS) is a new simulation technology which can connect the heterogeneous simulators at multiple locations create a consistent, time and space coherent synthetic world through data exchange among simulation entities. It is the main task to realize the simulation of "Intelligence Reconnaissance and Data Fusion System" using distributed interactive simulation technology. On the basis of studying the DIS (Distributed Interactive Simulation) and HLA/RTI, this paper presents a data fusion system simulation model base on CORBA. The model uses the method that separates the entity engine from the entity attribute and entity behavior to improve the agility for study and modeling of simulation. Through the introduction of broker, the paper presents the publication/broker/subscription model and realizes the interoperability among simulation entities. The experiments prove that the method not only provides the availably data fusion simulation datum but also improves the agility, expansibility and applicability. Finally, the paper describes the important arithmetic in the system.
