Simulation Of Ground Radar Networking System Based On HLA

The number of electronic countermeasures,tactical communications,command and control and other information equipment will continue to increase in the future battlefield,and the system will become more complex.How to realize a large-scale,scalable and highly interactive simulation system puts forward new requirements for computer simulation technology.Using the powerful distributed simulation network communication capability of High Level Architecture(HLA),large-scale complex systems can be simulated.In order to adapt to the development trend of large-scale,multi-functional radar systems and the systematic and dynamic development of radar networking,this thesis builds three ground radar simulation models based on the HLA distributed simulation framework,including search and warning radar,target indication radar and air defense.The guidance radar realizes the collaborative work of a single radar detection and a multi-radar network.The main work contents of this thesis include the follows points:1.Using the modular design concept,the ground radar simulation system is divided into different functional modules,including target information acquisition module,functional-level signal processing module,data processing module,and adaptive task scheduling module.The modeling analysis of each module is carried out and the realization process is given,including: line-of-sight judgment,terrain occlusion judgment,resolution calculation of the target acquisition module,detection model,suppression interference model,and detection error model of the functional-level signal processing module.The process of preprocessing,track management,tracking and filtering of the data processing module is given,and the method of implementing the adaptive scheduling module is given.For active spoofing jamming,the realization method and process of data fusion anti-jamming are given.2.Formulated a typical ground radar network air defense system plan,designed the search and warning radar,target indication radar and air defense guidance radar working methods,and developed the display and control terminals corresponding to the three radars by using the Qt platform.Based on the HLA distributed simulation framework,the realization method of the ground radar networked air defense system is given,and the federation structure,FOM,and member timing are designed in detail,and the communication and interoperability among members are realized.3.On the HLA-based XX distributed countermeasure simulation platform,the radar simulation example test was carried out,different countermeasure scenarios were planned,and the multi-target detection capabilities of each radar were verified through each radar display and control terminal and situation.In the case of active interference,whether there is an effect of taking anti-jamming measures,and for active spoofing interference,the use of networking data fusion effectively eliminates false targets.
