Research On The Disposal Effect And Secondary Disaster Assessment Of UAV Countermeasure System

In recent years,the phenomenon of unmanned aerial vehicles has been rampant,and the control of no-fly areas has become more difficult,especially in civil aviation airports with stricter requirements for low-altitude airspace.To effectively deal with illegal drones,the drone countermeasure system plays an important role.Carrying out the evaluation of the UAV countermeasure system can provide a comparison platform for countermeasure systems with different technical bases,provide a basis for the application of countermeasure systems,and promote the development of the countermeasure industry,which has strong practical application value.The main research content It can be summed up in five points:(1)Studied the UAV countermeasure system.The existing UAV countermeasure systems are comprehensively analyzed,the principles and characteristics of different countermeasure systems are clarified,and the functions of the UAV countermeasure system are classified according to the function form of the UAV countermeasure system.The selection of countermeasure test equipment provides theoretical support.(2)Established an evaluation system for the UAV countermeasure system.Through the research on the disposal process of the UAV countermeasure system,combined with expert opinions,the UAV countermeasure system disposal effect evaluation system and the postdisposal secondary disaster evaluation system are established,and the mathematical model of each evaluation index under the evaluation system is constructed.the collection methods and analysis methods of different index data are proposed.(3)Completed the UAV countermeasure test.The UAV countermeasure test plan is designed,the environment construction and test configuration of the UAV countermeasure test are planned,the UAV countermeasure test is carried out and the test data is collected to establish the UAV countermeasure image database.(4)Advance the detection and tracking method of targets in UAV counter-image data.Aiming at the difficulty of quantifying the fire,impact and stability indicators in the secondary disaster assessment in the evaluation system of the UAV countermeasure system,the edge detection method based on Canny operator and the grayscale morphology method are introduced,and the unmanned person in the image data is introduced.The machine target is detected and the relevant index data information is extracted.In addition,a target tracking method based on position correlation is proposed,which correlates the target before and after the frame,and extracts the trajectory change information.(5)Advance the evaluation method of the disposal effect of the UAV countermeasure system and the evaluation method of the secondary disaster after disposal.Based on the evaluation system of UAV disposal effect and secondary disasters,the algorithm model of FAHP and TOPSIS is introduced.In summary,in view of the problem of research gaps in the field of UAV countermeasure system evaluation,this topic proposes the evaluation system of UAV countermeasure system and the analysis method of each evaluation index,and establishes an assessment model on the disposal effect and the secondary disaster after disposal,and the evaluation model is analyzed and verified by conducting the UAV countermeasure test,and the results show that the assessment results are in line with the expectations of the expert group,and the evaluation model is feasible.It can effectively solve the problem of disposal effect of different UAV countermeasure systems in the process of countermeasures and the assessment of secondary disasters after disposal.
