Implementation of Ballistic Trajectory Calculation with Digital Signal Processor in Tank Fire Control System

Aiming at the defects of the trajectory approximation that has been widely used in the present tank fire control equipment, we present the improving algorithms by direct resolving differential equation in trajectory calculation. The digital signal processor (DSP) is introduced in the algorithems' hardware environment to improve the real-time propertiy. The experiments are also made. The results show that the algorithm with DSP can significantly increase the accuracy and speed of on computation. The algorithem shows a good propect in its applications in tank fire control system.
