Abstract	In order to eliminate the measure error that caused by the projectile that cannot fly across the sky-screen vertically in the sky-screen velocity measure system, correlation analysis method was put forward to extract the time information of the detecting screen, which can reduce the measuring error of time and improve the measurement accuracy in the whole measure system. In this paper, the principle of the sky-screen velocity measure system and the influence factors were analyzed. The correlation analysis was researched and used to extract the time moment in detection screen, the output waveform when projectile flying detection screen was gathered by computer; the waveform correlation of two sky-screens in measure system was analyzed, the time when projectile flying two screens was calculated. Combining with the actual distances of the two sky-screens, the flying velocity of the projectile can be gain. Through the experiment, the time error got from the correlation analysis is less than 0.1us, and the velocity error is less than 0.2%.
