A Research On The Design And Experiment Of Antiaircraft Artillery Fire Control System-Based On Dual-computerCooperation

In the process of China’s information technology revolution in military affairs, the army has strong demand fordigital fire control system. However, there still exist a lot of old artillery fielded which undertake the important task of air defense in a short time. Therefore, it is necessary to carried out digital transformation on the old artillery which is in order to maximize the performance of existing equipment and improve combat effectiveness. This study aims to achieve the digital transformation for the old anti-aircraft fire control system. All this above is the general idea of the current anti-aircraft fire control system design.This research aims to use digital fire control system for target acquisition. Dock the signal interface through digital transformation. By using photoelectric detection technology to capture and track the targets. Then analyze the target information and firing data. Finally, the digital signal interface will sent the firing data signals directly to the old artillery. This thesis focuses on the algorithm of artillery fire control system and the architecture ofhardware. The algorithm is mainly based on Kalman filter model, the procedure of least-squares fitting track, the building process of ballistic model on firing Table s offline and firing data and revision process. Furthermore, the author uses Matlab simulation, a mathematical tool, to verify the effectiveness of the algorithm.Hardware architecture relies on dual-computer collaborative architecture model. In this thesis, the author elaborates the design of both hardware architecture and software architecture. By sharing RAM-based logic control mechanisms, the system interact the data and status from both the hardware and software. Meanwhile, the system carries on the logic simulation analysis on the basis of ModelSim.This thesis firstly carries on the fire control system simulated analysis on the target data which is inputtedfrom the front-end analog. The simulated data and results are presented in tabular form and they are systematically analyzedthe damage probability. Secondly, through simulated data analysis and shooting range firing experiments,this design is demonstrated to be feasible and it can meet the requirements of the system specifications.Through the research on this design and the simulated experiment, it will offer great help in digital transformation on the old artillery.
