As the development of electronic reconnaissance equipmentthe radars are facing more and more threats in battlefieldthe technology of netted firecontrol radar can protect radar from the threats to some extent.In order to simulate the effect of this technologythe interactive simulation method is used to simulate the netted firecontrol radar target tracking system.Firstthe technology of netted firecontrol radar is introduced.Thena simulation method of netted firecontrol radar target tracking system is proposed based on High Level Architecture (HLA)and the federate abilitythe parametersand the publish / subscribe relationship of simulation system is given.The main flow chart of simulation system is also given.
