Multi-Missile Curvature Cooperative Guidance Method Based on LSTM-IMM Target Tracking

Multi-missile interception of maneuvering targets requires accurate prediction and impact-time coordination under fixed missile speed. This study couples LSTM-IMM tracking with active curvature planning. LSTM generates a time-varying IMM transition matrix from measurement features, and the guidance law converts fixed-speed coordination into curvature and normal-acceleration allocation. Comparisons, sensitivity tests, Monte Carlo simulations, and five engagement scenarios verify tracking, mode recognition, real-time feasibility, and interception without speed regulation.
