Description
Summary:Optimal missile avoidance is analyzed with a two-dimensional linearized kinematic model. It is shown that inclusion of a control-effort penalization term in the payoff function leads to extend the domain of validity of the trajectory linearization. The required values of the weighting coefficient of the control penalization and the resulting loss in the optimal miss distance are evaluated. A recursive algorithm for the numerical solution of the modified optimal avoidance problem is presented. The optimal solutions obtained for the linearized kinematical model are compared to results of non-linear simulation.
