Situation maintenance-based cooperative guidance strategy for intercepting a superior target

A situation maintenance-based cooperative guidance strategy is proposed to intercept a high-speed and high-maneuverability target via inferior missiles. Reachability and relative motion analyses are conducted to develop and pursue virtual targets, respectively. A two-stage guidance strategy under nonlinear kinematics is developed on the basis of virtual targets. The first stage optimizes the coverage and collision situation by pursuing virtual targets under specific angular constraints. The second stage subsequently intercepts the superior target based on the handover condition optimized by the first stage. Numerical simulation results are provided to compare the effectiveness and superiority of the proposed strategy with those of the reachability-based cooperative strategy (RCS), coverage-based cooperative guidance (CBCG) and augmented proportional navigation (APN) under various maneuvering modes.
