The performance of methods for track refinement from break-up events involving ballistic missiles may be degraded by certain unexpected ?off-nominal? behaviors. For example, if the parent object is a rotating rigid body, it possesses rotational kinetic energy that could be released as translational kinetic energy during a separation event. The conversion of rotational energy to translational energy can result in unexpected velocities for the separation objects. To accommodate this ?off-nominal? behavior in the track refinement procedure, we propose a solution founded on a model of the underlying physics of rotating bodies. The value of our approach will be demonstrated during the Phase I effort using Monte-Carlo simulations of off-nominal break-up events. Approved for Public Release 14-MDA-8047 (14 Nov 14)
