Abstract
A time-difference process and apparatus for scoring supersonic aerial projectiles, such as military aircraft air-to-ground strafing projectiles fired at a strafe target, by detecting and measuring the acoustic shock waves propagated by the projectiles. The process and apparatus uses an array of at least six dynamic transducers to independently sample each projectile shock wave and transmit sampled signals to at least one all-purpose digital computer. The time-differences of arrival of the shock waves at each transducer are processed by an iterative algorithm implemented by the computer. The algorithm calculates projectile impact point, projectile velocity and other useful scoring data. The scoring data are used to quantitatively score the number of hits or misses by the strafing projectiles on the strafe target. Scoring data and other projectile data are selectably indicated to the operator by remote display and printout.
