Research On Shipborne Target System Based On Acoustic Principle

At present,the manual method is mainly used to count the results of target shooting when the soldiers carry out the target shooting training at sea,and the manual target shooting has some defects in the target shooting process,such as prolonging the target shooting time,wasting human resources and misreporting the target.In order to solve the above problems,this paper designs a shipborne target targeting system based on acoustic positioning by analyzing the existing different target targeting systems,which can meet the requirements of target training at sea and improve the shooting level of soldiers.The following studies are carried out on this system:(1)A multi-redundant array positioning model is proposed.Based on the conventional L array and square array positioning models,a multi-redundant array positioning model is proposed for Marine target shooting application scenarios.By analyzing the formation process and spectrum characteristics of the projectile shock signal,it is determined that the velocity of the bullet reaching the target surface is the key factor affecting the target accuracy.The model can improve the accuracy of the target by measuring the speed of bullet in real time.The positioning model strategy of multiple redundant arrays is constructed to improve the reliability of the target system.(2)Carry on the target system hardware overall scheme design.According to the specific function of shipborne target targeting system terminal and the performance index needed to realize the function,the overall design scheme of target targeting system is given.The selection of each functional module of the target system is completed,and the circuit of the functional module of the target system and the main control peripheral circuit are designed,and finally the circuit board of the controller is drawn.(3)Realizing the software structure framework design of shipborne target system.The STM32 controller program is designed by Keil uVision5 development environment,the target system software is designed by Visual Studio development environment,and the database function is added.(4)Complete the construction of the hardware and software system of the whole shipborne target targeting system,and test the function of the system to verify the reliability of the whole system.Experimental results show that the target error of the shipborne target reporting system designed in this paper is 2 cm,which meets the actual target shooting needs.
