Research On Time Management And Data Distribution Management In Information Countermeasure Simulation System Based On HLA

High Level Architecture is the frontier of distributed interactive simulation; itrepresents simulation technology’s orientation. It emphasizes interoperability andexpansibility of the simulation system. The interconnection of different types ofsimulation members can be supported by HLA. In order to meet the demand ofsynchronicity and expansibility of information countermeasure simulation system, HLAis introduced to information countermeasure simulation system. Time management (TM)and data distribution management (DDM) are the keys of improving the interoperabilityand scalability of simulation system, so the TM and DDM are cores of this paper.The model of information countermeasure simulation system is established basedon the further research of HLA and Run-time Infrastructure. Based on this model, thestructural model of navigation countermeasure simulation system and communicationcountermeasure simulation system are established to meet the special demand of thesesimulation systems. TM is the key of implementing synchronicity of the simulationsystem and directly influences the reliability of simulation results. On the basis ofstrategy of TM, The advancing mode of information countermeasure simulation systemis summarized to meet the demand of information countermeasure simulation system.The length of simulation step and the time slice of interference are further studied. Forthe sake of improving the performance of simulation system, the mechanism of DDM isdescribed, and the matching algorithm is also studied in depth. Based on this, thesimulation areas of navigation countermeasure simulation system and communicationcountermeasure simulation system are divided. In order to validate the efficiency ofTime Management and Data Distribution Management that the paper proposed, thesatellite navigation countermeasure simulation system and frequency hoppingcommunication countermeasure simulation system are established respectively. Thefunction of satellite navigation countermeasure simulation system and frequencyhopping communication countermeasure simulation system are tested.
