Methods to measure the parameters of the flying objects via to the four-light-screen combined array

In order to meet the demand of measuring the impact location dispersion of flying objects, a measurement method basing on the four-light-screen combined array was put forward. The composition of the system was introduced, the measurement principle was analyzed, and the formula was deduced. When two or more flying objects going through the light-screen array at the same time, the identification algorithm of time sequence and projectile images was discussed according to that the principle of straight line projectile ballistic and the imaging principle of the array CCD. Finally the algorithm was verified on Matlab, the results show that the method presented is availability and it can measure the impact location dispersion parameters of the flying object.
