Abstract

In order to solve the measuring difficulties of position coordinate in target space of high-speed flight, the dissertation applies for the measurement theory of N-shaped multi-screen array. Through developing space plane equation of every detection plane and then combining this equation with unknown parameter trajectory space linear equation can acquire the solving formula of high speed target space location. Making use of the law of error propagation analyses the theoretical error of the high-speed target space location coordinates calculation formula and going on digital simulation can reach the distribution of errors of X , Y coordinates. While the error of Z -coordinate is double of the error of target distance. Applying for the experiment of live bullets shoot can manifest the correctness of coordinate measurement formula provided in the article. The errors of distribution and digital simulation are coherent..
