Improved Sparrow Search Algorithm Applied to Multi-stage Weapon Target Assignment

Air defense operation is important in modern warfare. We study the weapon target assignment(WTA) problem and corresponding heuristic algorithm. Three-stage WTA model was proposed and novel objective function was constructed to emphasize the different benefits of shooting down missiles at different stages. The original sparrow search algorithm(SSA) was improved and the experiments we performed in this paper showed that the modified algorithm is more effective in solving the three-stage WTA problem.
