Abstract

Six-light-screen vertical target is an ideal equipment for the projectile flight parameter measurement of the rapid-fire weapon, the light-screen-array model of this kind of equipment is mainly divided into double V shaped and double N shaped, which build different light-screen structure in the space respectively. By recording the time that the projectile reaching each light-screen, and combining with the known spatial structure of the lightscreen array, the flight parameter of projectiles can be measured. Due to the measuring formula is determined by the light-screen-array model, the error influencing factors are considered under different model, and the influence of each factors were analyzed in the selected target plane, respectively. The error distribution were compared under the same condition of each error influencing factors. Then the combined error are calculated and the combined error distribution in the 1m×1m target plane were estimated. The research can provide a useful reference for error analysis in practice, and provide new ideas for improving the measurement precision of rapid-fire weapons.
