Weapon Launch Decision-Making of Armed Helicopters Based on Improved RWS-WOA Algorithm

To meet the aiming attack requirement in the high maneuvering flight of armed helicopters, a weapon launch decision-making scheme for armed helicopters is proposed in this paper based on an improved roulette wheel selection whale optimization algorithm (RWS-WOA). The weapon launch decision-making is to obtain the best weapon launch envelope and the best attack point on the guide trajectory. Based on an integrated fire/flight control system and the air-ground combat situation assessment, a priority function of the weapon launch envelope is established. The weapon launch envelope is the prior range on the guide trajectory. Then, according to the requirement of quickness and accuracy, an improved RWS-WOA is introduced, which is efficient to explore potential envelopes and converge to the optimal solution. Finally, the effectiveness of the proposed method is verified by a simulation example.
