Summary:A system and method for determining the track of a projectile use a thermal signature of the projectile. Sequential infrared image frames are acquired from a sensor at a given position. A set of frames containing spots with characteristics consistent with a projectile in flight are identified. A possible projectile track solution for said spots is identified. A thermal signature value for each pixel of each spot of the possible solution is determined. The determined thermal signature is then compared to an actual thermal signature for a substantially similar projectile track to ascertain whether the determined thermal signature substantially matches the actual thermal signature, which indicates that the possible projectile track solution is the correct solution.
