Optimal Evasive Maneuvers in Conditions of Uncertainty

Optimal missile avoidance by an evader not having information on the relative state is analysed. This problem is equivalent to the homing of a missile of known parameters against a randomly maneuvering target. The objective is to maximize the R.M.S. miss distance by selecting the optimal frequency o...

Description
Summary:Optimal missile avoidance by an evader not having information on the relative state is analysed. This problem is equivalent to the homing of a missile of known parameters against a randomly maneuvering target. The objective is to maximize the R.M.S. miss distance by selecting the optimal frequency of a periodical maneuver with random initial phase. Comparison to results of missile avoidance with perfect information shows that the maximized R.M.S. miss distance can reach 60-80% of the optimal deterministic value.
