For the fall of trajectory and the scatter of projectiles,there is larger error between the true value and the measured data by radar or Sky Screens.A new method presented here consists of two special three-skyscreen systems on two supporting structures and a device for signal processing to record the time of the projectile flying through the sensing screens.According to the parameter of geometrical structure and six time data,the special angle of flying direction and the velocity are obtained.Contrasted with the radar and the general sky-screen system,the method presented here has higher precision.
