Abstract

A space-based cruise phase defense strategy is proposed for near-space hypersonic vehicles. Considering the properties of near-space defense, a valid zero effort interception handover (ZEH) region and its performance criterions are presented by analyzing the handover region, which connects the midcourse and terminal guidance phases. Based on the model predictive static programming (MPSP) theory and the terminal constraints of midcourse phase, a close-formed solution is derived as the command correction guidance law. The proposed guidance law is used for simulation. The simulated results show that a small velocity-ratio condition for terminal engagement is satisfied by ZEH. The proposed method can improve the computational efficiency significantly, and also meet the requirement of ZEH constraint. A large number of Monte Carlo simulations show the robustness of the guidance law against initial disturbances.
