In the design of multiple-impulse terminal correction submunition, in view of the intensively conflictive problem among the optimization objectives, three multi-objective optimization models based on the decision variants “initial height, initial velocity and the impulse of the single thruster controller" and the objective functions "the miss distance, the drop time, the angle of the projectile falling on the ground and the total consumed energy" were established, here terminal correction trajectory was taken as the object of research. The algorithm of MOEA/D was adopted in the simulation. The simulation results indicate that the Pareto frontier we get is suitable for real and engineering problems, which is helpful for designer to choose appropriate parameters to optimize trajectory and provides designers with great consultative value.
