In order to meet the tactical requirements of anti-ship missiles while achieving saturation attack, based on the idea of controlling missile launch sequence and launch interval, considering the influence of marine environmental factors on missile speed, a time cooperative method of attacking the single ship and the ship formation of the anti-ship missile is put forward. Then, based on the idea of controlling the missile’s flight range through route planning, the route symmetrical calculation model and the dynamic ellipse calculation model are established, and the model of dynamic ellipse calculation is proposed. Simulation results show that this method can achieve the goal of simultaneous launching of the salvoes on different flight paths, and solve the problem that the launching platform of the anti-ship attack needs to maintain a stable position for a long time and improve the efficiency of missile attack action.
