Abstract: A method, computer program product, and target tracking system for obtaining a first kinematic state measurement of a first projectile detection event from a first sensor. The first kinematic state measurement includes a first time measurement and a first state vector. A second kinematic state measurement of a second projectile detection event is obtained from a second sensor. The second kinematic state measurement includes a second time measurement and a second state vector. If it is determined that at least a portion of the first kinematic state measurement and at least a portion of the second kinematic state measurement define at least a portion of a flight trajectory orbital ellipse, the first projectile detection event and the second projectile detection event are defined as portions of a flight trajectory of a single ballistic projectile.
