Abstract:

In order to meet the demand of measuring the impact location dispersion of a double barrel canon automatically, the principle of the seven-light-screen array was put forward. The seven-light-screen array can be set up by adding a light screen in the middle of the double 吁type six-light-screen array. Based on the principle of that the firing position is on the corresponding projectile ballistic line, an algo- rithm of identifying the time sequence of the same projectile going through the seven-light-screen array was identified. The method was simulated and verified on MATLAB. The results show that the method is feasible and it can be used to measure the impact location dispersion parameters of the double barrel can- on.
