Multi-UAV Cooperative Detection Method for Ballistic Missile Boosting Section

For the cooperative detection of the long-range ballistic missile boosting segment, a multi-UAV cooperative detection method was proposed based on the dual-UAV cooperative detection, which combines the tentative maneuvering trajectory optimization with the triaxial separation IMM-EKF (TASIMM-EKF) filtering algorithm. Firstly, considering the influence of the position of the drones on the target positioning accuracy, the tentative maneuvering trajectory optimization strategy was proposed for the trajectory optimization of each detecting drone. At the same time, a three-axis separation IMM-EKF filtering algorithm was proposed. The simulation results show the proposed method can improve the state estimation accuracy effectively, shorten the estimation time, and have good performance for maneuvering target state estimation. It provides theoretical guidance and technical support for the next study of interception problems.
