    摘要: A method for determining the trajectory of a projectile on a ballistic trajectory includes creating a sequence of images of the projectile using a passive image sensor located at an observer; determining the time the projectile started on its trajectory; determining relative positions of the projectile's launch point, the observer, and an expected impact point; ballistically modelling the projectile; and tracking the projectile through the sequence of images using a track before detect algorithm.
