Synthesis of Mixed Guidance Strategy Sets Against Different Subsets Targets Strategies

This paper examines problem of synthesis of homing guidance law of the short range antiaircraft missiles. The presented research is based on the results of Shinar&#8217 ; s and Forte&#8217 ; s approach which refers to transforming very complex stochastic differential game to the matrix game with a saddle point solution in the domain of the mixed guidance strategies. The main research is addressed to the synthesis of the optimal mixed guidance strategies with the assumption that presents prior information about the target behavior. From this assumption entire set target strategies can be divided in to several subsets. In addition is discussed the effect of a target course on synthesis of the mixed guidance strategies. Furthermore is analyzed impact of calculation payoff matrix of the game based on 6DOF missile model against calculation based on linear plain model. As results, are evidenced that assumption about existence prior information on probable target maneuverability and electronic countermeasures, gives possibility to optimize several separate mixed guidance strategy sets for each subset of the target behavior. For this reason the results of the games are better than those, when this prior information is not presented. It is shown also that is reasonable to optimize several mixed guidance strategy sets for a different target courses.
