![]() ![]() ![]() From the point of view of targets, because the projectiles have the ability to selectively guide the targets, the targets also have the ability to control the mobile movement, so the targets are selective defense capabilities, and also have the ability to attack the projectiles coming from the air. ![]() Based on these two aspects, the damage of multiple projectiles to targets is a very important research point, which is also the mainstream trend of the current development of smart projectiles. Thus, the effectiveness of multiple projectiles on targets is optimized and improved. Through multiple projectile communication, the nearest target can be found to be damaged by the initiation explosion of projectiles, while other projectiles do not detonate, but continue to move forward, waiting for the next stage to meet new targets, and then detonate. On the other hand, in addition to passively detecting the echo information of targets, advanced projectile guidance is embedded with a communication module, which can detect the distance information between targets through multiple projectiles. The echo information detection device of the projectiles will obtain enough detonation control information, and control projectiles to explode, thus forming a warhead fragment group. On the one hand, when multiple projectiles attack the target, the echo energy formed by the projectiles in the process of approaching the target will increase with the decrease in the detection distance. The damage assessment of the intersection of the projectile and target has improved from how to effectively assess the damage of the warhead fragments formed by different projectile proximity distribution to target and how to evaluate the guidance effect of the interaction between the detection ability and communication ability of the projectile proximity. Simulations are performed to validate the feasibility and effectiveness of the proposed game damage strategy model and the solution method. The Nash equilibrium of the game is obtained by combining the particle swarm optimization algorithm and the interval number multiple attribute ranking method in the case of uncertain information, and then, a new optimal damage assessment strategy method of Offensive/Defensive Game of projectile and target is gained, the method to solve the Nash equilibrium value of the payment matrix is given. According to the information of both the projectile and the target, from the perspective of the gain of the projectile attacking the ground target and the gain of the ground target defense, this paper establishes the indicator function of offensive/defensive game of projectile and target intersection under uncertain information and constructs the payoff matrix of the confrontation game between the projectile and the target. This paper regards the projectile and target as two participants of the zero-sum non-cooperative confrontation game and studies an offensive/defensive game damage strategy modeling method when the projectile meets the target under uncertain information. The target damage assessment when a projectile is attacking a ground target under uncertain information is a difficult problem to solve, because the intersection-relative position of the projectile and target is a random distribution and the target damage is also uncertain in the intersection confrontation between projectile and target. ![]()
