WTA model study of air defense missile system based on particle algorithm

In order to solve the current target distribution of large amount of calculation, and the problem of real-time computing, we propose a new target assignment model to cooperate with the fleet of aircraft air defense firepower system. The model is based on a modern air defense stopped to shoot as the main BVR(Beyond Visual Range) air combat missions, the distance between the small fleet of aircraft characteristics, ignoring differences in the relative distance between the target aircraft in the fleet, created from the perspective of weapon types, thus reducing Solutions for small scale. Suppose a combat scenario, the general target distribution models and new models were analyzed and compared by particle swarm optimization algorithm, the results show that the model has a small amount of calculation, solving speed characteristics proved scientific and feasibility of the model.
