Abstract : This report summarizes the work performed by the Information and Control Group in support of Nike-X System Evaluation Studies. The results of a study on real-time implementation of the Kalman filter for estimating ballistic trajectories at endoatmospheric and exoatmospheric altitudes are described. In addition, analytical techniques for investigating and characterizing the sensitivity of filter performance with respect to parameter variations are discussed. Computer programs, based on the gradient method and dynamic programming, for calculating optimal guidance and control for an AMM are described. Finally, a study concerned with the problem of predicting the trajectory and impact point of a ballistic reentry vehicle is outlined. (Author)
