Research On Anti-unmanned Aerial Vehicle System With Netting

At present,the continuous popularity of UAV brings not only entertainment and convenience,but also accidents and related safety problems of UAV itself.However,the small size and high flexibility of UAV make it difficult to counter it.Therefore,the countermeasure of small UAV is still in the exploratory stage.In this paper,the development of anti-unmanned aerial vehicle(UAV)catching net system has been carried out,and the engineering realization and test have been completed.The main contents include:(1)Introduced the components and principles of the anti-unmanned aerial vehicle(UAV)catching net system,analyzed the specific functions of the electronic sights,the core part of the system,determined the design scheme of the electronic sights with the main control module of information processing as the core,and carried out the overall workflow design of the anti-UAV system.(2)The circuit design of the main control module of information processing is discussed in detail.The specific design of the core processor,the external memory device and the analogto-digital conversion circuit are given.The power supply circuit design is completed by analyzing the power demand.The miniaturized PCB implementation is completed and the signal integrity analysis is carried out.(3)According to the movement characteristics of the trawling missile,the resistance analysis is carried out,and the trajectory model is established.According to the trajectory model,the trajectory calculation is carried out by using the fourth-order Runge-Kutta method,and the trajectory calculation algorithm is designed.(4)For the main control module of information processing,the driver of driver A/D conversion chip is designed,the soft core of NIOS II for trajectory calculation is realized,the interface design scheme is given,and the operation control mode is designed,which drives the OELD display imaging.(5)Experiments are carried out on the engineering anti-UAV system,mainly including the counterweight bomb test and the live bomb test.The results show that the system can accurately capture the small UAV.
