Abstract:
The optimal interception trajectory of a generic anti-ballistic missile is rather close to a straight line, with final corrections that are needed in order to compensate for early measurements errors and possibly to respond to target evasive maneuvers. This, in principle, makes it possible to separate the launch timing and thrust optimization ("longitudinal") issues from the guidance and control ("lateral") problem. With a "good" selection of coordinates, the G&C process can be described by a set of linear differential equations, for which a full state feedback control can be constructed using "classical" optimization methods. In order for the solution to be effective, it is however essential for the system state model to be non-redundant, or "minimal" in some sense. Based on those concepts, we demonstrate a computerized G&C design method that can be applied to other types of interception missiles as well.
