An optimal control and estimation algorithm for missile endgame guidance

The design of an optimal guidance and control system for a short range air-to-air missile is undertaken. An optimal target tracking filter is used to track target position and velocity, and a Generalized Likelihood Ratio approach to maneuver detection is employed with maximum likelihood estimation techniques to estimate target acceleration. The estimated target variables are then used with a modified linear quadratic regulator to generate the required guidance commands to minimize miss distance.
