Study on the space burst point test system used in proximity fuze projectile

Aiming at the problems of existing device in measuring the projectile proximity fuze three-dimensional coordinate of space burst point. A system based on six light-screens principle and flame detector was presented. The system´s main detector includes two multi-screen sky screens and one flame detector. The six light-screens detector array is composed by six optical and photoelectric conversion parts of the two multiscreen sky screens. When the projectile passes through the six light-screens, the data acquisition instrument records the data of the analog signals produced by the sky screens. The projectile velocity V, angle of incidence θ and γ, impacting coordinates X and Y all can be got by processing the signal. The projectile´s explosion time T can be detected by the flame detector. And then projectile´s three-dimensional coordinate of space burst point can be calculated by above-mentioned parameter. It is proved by the experiment that the system is stable and reliable, and can meet the demand of the shooting range well.
