Trajectory optimization for a missile with strap-down seeker against hypersonic target

摘要

Trajectory optimization against hypersonic ballistic target is performed for a missile with strap-down seeker. For successful interception, the hand-over point of the homing phase from midcourse phase should be properly determined, which is obtained by trajectory optimization in this study. Constraints on control inputs are introduced to consider the property of strap-down seeker. The direct method is used to solve the trajectory optimization problem. Numerical simulation is performed to demonstrate the performance of the proposed method.
