The application of digital signal processing (DSP) for the real time solving of artillery fire control exterior trajectory

Method of gain firing data by calculate the group of differential equation has the advantages of high repeatability and high accuracy, But much of the CPU time is occupied by the task of re-iteration in computational processing. Therefore, it is not the real time processing. This paper introduces a method to quickly determine angle of firing by iteration method, which realizes Runge-Kutta method for the equations of exterior ballistic according to the model of mass center motion of projectile. Moreover, it also provides the flow of real-time integral solution and be proved by the simulation of MATLAB. Its accuracy satisfies the requirements. This work can be as reference for the design of opt-electrical fire control system and the demonstration work.
