In order to accurately measure the target accuracy of the projectile's position, this article used the intersection measuring system with dual liner CCD and introduced the working principles of this system, and the calculated formula of target coordinates had been demonstrated. We analyzed the components and the positioning ways of each measurement module, on the basis of which the measuring system had been established. The target accuracy of the projectile's position is 0.041 7 m (Direction error probable) and 0.031 9 m (Level error probable). The measured value compared with the calibration value in the mm level difference, indicates that the system accuracy is ideal. So the development of this measuring system is successful, and it was able to accurately measure the target accuracy of the projectile's position.
