The Principle and Analysis of Flying Projectile Coordinate Measure in Multi-screen Target

Because the optical scoring system that only can apply in the low altitude that can´t meet the need in current, and it can´t measure the Z coordinate that is the direction of flying bullet. In order to solve the problem of three direction coordinator´s measure when the flying pullet exploding in the high altitude, the measure principle of the multi-screen target that is composed of the high sensitivity photoelectric detection target was put forward, the mathematic model of measurement system was set up, and the high sensitivity flash optic-electric detection target was used to measure the Z coordinate that the four cross screen measure system can´t realize, the differential method was applied to analyze the error of measurement system, which come from the intersection angle, the thick of screen, the time and distance of measuring. Through error´s analysis, the measurement system can satisfy the request.
