On Developing a Robust Missile Guidance Algorithm

In this paper we consider the problem of exoatmospheric missile/target engagements with imperfect state information. We present a newly developed robust guidance algorithm which achieves better hit performance and less fuel consumption than a proportional navigation (pro-nav) guidance algorithm for certain engagement scenarios. These preliminary results lead us to believe that robust guidance algorithms can eventually be developed which will globally outperform existing guidance algorithms in dealing with uncertainties.
