Abstract
The performance measurement of hypervelocity projectiles in flight is critical in ensuring proper projectile operation, for designing new long-range missile systems with improved accuracy, and for assessing damage to the target upon impact to determine the projectile's lethality. We are developing a modular, low cost, digital X-ray imaging system to measure hypervelocity projectile parameters with high precision and to almost instantaneously map its trajectory in 3D space to compute its pitch, yaw, displacement from its path, and velocity. The preliminary data suggest that this system can render an accuracy of 0.25° in measuring pitch and yaw, an accuracy of 0.03" in estimating displacement from the centerline, and a precision of ±0.0001% in measuring velocity, which is well beyond the capability of any existing system.
