| Abstract: | The velocity measuring system of the double projectiles based on the data acquisition card with the optical screens is put forward.The composition and measuring principles of the measurement system is expatiated in detail.The correlation algorithm in mathematics is artistic used to process the signals of the double projectiles,and the precision of the interval between the start-time and the end-time is much improved.The testing result of the ball firing has proved that the measurement system has much higher... |
