SA-DPSO-based Weapon-target Assignment for Cooperative Air Defense with Anti-aircraft Gun-Missile Weapons

For the weapon-target assignment problem of anti-aircraft gun-missile weapon formation air defense, a weapon-target assignment model was developed for anti-aircraft gun-missile weapon formation according to the different fire characteristics of anti-aircraft missile and anti-aircraft gun system. The model gave sufficient consideration to the damage zone of anti-aircraft gun and missile as well as the weapon-target join point, and the assignment result allows anti-aircraft gun-missile weapons to fire missiles and anti-aircraft guns at the right moment. On this basis, the method of Simulated Annealing-Discrete Particle Swarm Optimization (SA-DPSO) was proposed to solve the weapon-target assignment for formation anti-aircraft. The simulation result showed good rate of convergence and global searching ability of the algorithm.
