Research On Track Fusion In Multi Equipment Joint Command And Control System And Implementation Of System

With the rapid development of science and technology,the battlefield situation is becoming more and more complex,and various threats in the battlefield are increasing,especially the emergence of small and medium-sized UAVs,with the advantages of small fuselage,strong mobility,adapting to complex terrain,low combat cost and so on,has brought great challenges to the modern air defense system.In order to effectively deal with the challenges brought by UAV,this paper designs a command and control system of multi equipment joint operation.The system can access radar equipment,photoelectric equipment,microwave weapons and other equipment at the same time,and has the functions of guidance,command,coordination and control,so that the equipment has systematic combat capability.As the core of the whole system,command and control system determines whether multi equipment cooperation can play a role.This paper mainly studies the track association,track fusion of multi radar equipment and the system design and modeling in the implementation process of command and control system,and finally successfully develops the command and control system.In this paper,we will discuss:Firstly,this paper proposes an FCM track correlation algorithm based on the historical state estimation of the target.Due to the ambiguity of the track correlation,the fuzzy Cmeans clustering algorithm based on fuzzy theory is studied.Considering that the algorithm only uses the track information at the current moment,the effect in dealing with actual problems is not satisfactory.Therefore,an algorithm combining the historical state information of the target is proposed,and the effectiveness of the algorithm is verified by simulation.Secondly,this paper improves the method that only one node information can be fused at a time in distributed track fusion,and proposes a distributed fusion algorithm based on the concept of waiting window.In this method,the received node information is saved by waiting window,and then when the window is full,the track is grouped and fused by merging idea,so that the fusion center can process node information in parallel,and can process multiple node information received at a certain time on the premise of ensuring the fusion speed.Finally,a multi equipment joint command and control system is implemented.Firstly,through the analysis of the function of the command and control system,the architecture of the system is proposed,and then the system is modeled to realize the command and control system which can receive data,process data and make decisions.This paper also realizes the situation display software with the help of the situation display tool of XXX platform.The multi equipment joint command and control system studied in this paper has passed the simulation practice.
