Abstract : A systematic procedure is used to design Kalman Filters for a hypervelocity missile system. The procedure includes truth model development, state space model formulation, filter tuning and Monte Carlo analysis. The study is based upon a planar engagement of highly dynamic missile, a constantvelocity aircraft, and a stationary target. Two lineofsight filters are developed using the rotating aircrafttotarget lineofsight frame as a reference and two inertial filters are developed using an inertial frame reference. The angle between the aircrafttotarget lineofsight and the aircrafttomissile lineofsight is the only physical measurement processed by the filters. Due to observability considerations, the inertial filters also process additional pseudomeasurements of range. The filters are compared by calculation of miss distance statistics, probability of kill, and computational loading. (Author)
