| Self-propelled artillery weapon system is the main weapon of the terminal defensive combat,it plays an important role in the terminal defensive combat,its performance index directly affects the weapon system combat capability,so it is important to study its performance index.There are many kinds of performance indexes of self-propelled antiaircraft gun weapon system,and the target process of self-propelled artillery weapon system is divided into two stages: search detection stage and attack damage stage,Therefore,this paper chooses the performance index which plays an important role in these two stages,that is,the distance of the photoelectric system in the search stage and the miss of the antiaircraft gun in the attack stage,and implements the simulation calculation system of the photoelectric system and the calculation system for the miss of the antiaircraft gun.The main research work and results achieved are as follows:(1)The simulation calculation part of the photoelectric system’s function distance.The influence of atmosphere on the distance of photoelectric system is studied in detail.Through the establishment of empirical formula model and the use of atmospheric radiative transfer model software to calculate the atmospheric transmittance,the distance simulation theory of various subsystems(television system,infrared system,laser System)in the photoelectric system are studied in depth,and then the distance simulation theory of various subsystems in the photoelectric system are established.(2)The simulation calculation part of the miss of antiaircraft gun.The related principles of flight target track generation,fire control calculation and projectile trajectory modeling are studied in detail.In this paper,a track prediction method based on an improved grey residual model is proposed,and a method for solving the miss distance of an antiaircraft gun is proposed.And the flight target track generation model,the fire control model and the trajectory model of projectile are established,and the solution to the data prediction problem is given.Aiming at the future point of antiaircraft artillery hit,this paper puts forward an iterative method to obtain the target future point.(3)System implementation part.This paper designs and implement the simulation system of the photoelectric system’s function distance and the simulation calculation system of the antiaircraft gun miss.In the simulation system of the function distance of photoelectric system,the user interface is drawn with MFC,the parameter setup of MODTRAN software is visualized,the problem of Tape5 file setting parameters is solved,and the problem of the long time for the implicit call MODTRAN software in the program is discussed.The solution of using empirical formula in the case of low precision is given,in order to facilitate the analysis of simulation results,the system setup and production data are stored by using SQL Server database.In the simulation system of antiaircraft gun miss,use Access database to set up and store track,and the display interface of the system is designed by OpenGL drawing technology,and the Miss distance is shown visually.(4)Simulation and result analysis part.Several experiments on the simulation system of the photoelectric system and the calculation system of the distance of the antiaircraft gun are carried out.The simulation results show that the system can meet the demand of the photoelectric system and the distance of the antiaircraft gun,and can analyze the influencing factors of the photoelectric system,and the calculation of the distance of the antiaircraft gun is more accurate.It can provide reference for the design and demonstration of self-propelled antiaircraft gun weapon system. |
