Paper Abstract

The test of firing dispersion needs to measure the bullet position on a target. But the trajectory ot the bullet requires normally incident on the scheduled panel in the conventional automatic location target measuring device, so it is more difficult to promise completely. The large errors of measure result will be got when trajectory and panel are not vertical. A kind of multiple light screens arranging structure is presented in this paper for resolving this problem. The method of space analytic geometry is used to solve the ballistic equation of bullets, which go through the target area with arbitrary direction. Accordingly the coordinates of the point of intersection is got, which trajectory with specified screen.The measuring principle is givern, and the measuring precision is analyzed.
