Abstract:	The mirror deflection speed of the existing ballistic tracking system is only determined by projectile discharge velocity, which cannot be real time corrected according to the actual position of the target during the tracking process.In order to solve this problem, a ballistic tracking system is designed that can correct the deflection speed of the mirror in realtime based on the target position. The system uses the elevation angle attitude shooting method to expand the field of view, proposes a target tracking algorithm based on background motion compensation, and constructs a mirror deflection model according to the relationship between the tracked projectile motion position and the mirror deflection angle. The experimental results show that the designed system can correct the mirror deflection speed in realtime according to the position of the projectile in a picture so as to achieve the purpose of keeping the projectile in the center of the picture.
