ABSTRACT:
A device for assessing an impact of a projectile with a target using optical radiation from the flash of the impact. The invention includes an optical radiation detector, which detects optical radiation from the impact flash using optical, electronic and optoelectronic devices. The optical radiation detector is situated on a tank firing the projectile at a target. Further included is an optical radiation augmenter, which is a pyrotechnic material, mountable on a projectile, for augmenting the flash of the projectile impact with the target. By analyzing the signatures of pyrotechnic materials using the optical radiation detector, one can easily identify which projectile impacted the target, determine a distance traveled by the projectile, and assess the projectile impact by ascertaining whether the projectile perforated the target.
