Cooperative interception of multiple missiles outside the atmosphere based on predicted hit points

According to the characteristics and requirements of intercontinental missile midcourse interception, an attack time controllable cooperative guidance structure based on the predicted hit point strategy is proposed. Considering the real-time requirements of missile interception, a calculation method for predicting hit points based on dichotomy is proposed. This algorithm can significantly reduce the calculation time and reduce the computational burden of the on board computer. The lead-follower structure is adopted. The lead-on missile uses traditional proportional guidance to quickly approach the predicted hit point. The follow-up missile adjusts the trajectory according to the remaining flight time information transmitted by the lead-on missile to meet the requirement of hitting the target at the same time as the lead. The simulation results show that the use of the guidance structure can effectively achieve cooperative interception, and meanwhile, the prediction hit point calculation is accurate and fast, which verifies its good performance.
