Predictive missile guidance

Guidance to intercept a manenvering target is considered. Uncertainty in th e predicted target position at interception is handled by constructing a Ga ussian-sum approximation to the probability density function of that positi on. A guidance framework inspired by model predictive control is presented, with the objective of maximizing the probability of successful interceptio n, and simplifications to make the computations feasible are suggested, The scheme is extended to the multitarget Ease, incorporating uncertain inform ation on target identity. The multitarget procedure allows compromise betwe en progress toward the selected target and keeping as many targets reachabl e as possible. Simulation results illustrating performance improvements ove r conventional guidance are presented.
