The Software Design Of The Laser Ranging And Tracking System

With the development of Opto-Electronic countermeasure technology,the laser ranging and tracking radar system plays an increasingly important role in modern warfare.The key component of laser ranging and tracking radar is its control and application software.The function of software module is to replace manual operation,the full automatic control of the working process of the radar,detection of laser ranging tracking radar data processing analysis,judgement,prediction of target motion state,and it can adjust and set the radar scanning strategy,it also displays some information such as location and distance of the enemy target.This paper is to carry out the research and preparation of the software.On this basis,the paper also focuses on how to improve the system's optical reconnaissance ability,reduce the random noise in target tracking,improve tracking accuracy and other issues.This paper firstly studies the target tracking algorithm used in the laser ranging and tracking radar system.Propose the Kalman Filter algorithm in the linear system dynamic model,and carry out MATLAB simulation and analysis.In the nonlinear system dynamic model using EKF and UKF conducts data filtering processing,and uses MATLAB simulation and analysis.Simulation results show that Kalman Filter algorithm can filter the data of linear system well and reduce the error caused by random noise in the measurement process.For the nonlinear system model,EKF and UKF can effectively smooth the error caused by random noise.And with the increase of sampling times,the filtering effect is obvious,which can meet the real-time tracking of moving targets.The paper also analyzes he laser ranging and tracking radar system framework in detail,and proposes the implementation scheme of optical search.And we built the system's intelligent software terminal platform with Visual Studio 2017 under the Windows OS,manage the system user information with SQL Server 2008 R2 database,and complete the software terminal research and development.In terminal software development processing,for solving the information security of the user,we propose ciphertext password solution.In terms of PC and microcontroller communication,multithreaded programming scheme is put forward,and we add exception handling mechanism to the system software to solve possible system exception and man-made exception,maximumlly guarantee the robustness and stability of the terminal software.The paper also uses the black-box testing method to test the functional modules of the developed system software terminal and evaluates the test effect.Terminal system structure is reasonable,the results show that,the software can be able to complete the system login and exit,file management,system debugging and data processing operations,such as realizing the real-time track of the optical reconnaissance and target,etc.In addition,a technical processing scheme is proposed for data filtering and interface scanning.And the software program of the exception handling mechanism and garbage collection mechanism,make the system having good robustness,and ensure that the software system is functional and has good stability,and can meet the laser tracking system engineering for the actual demand.
