Abstract :
An extended proportional navigation guidance (EPNG) law based on Lyapunov stability is proposed applying the concept of virtual target and 3-dimensional pursuit-evasion model. This guidance law can satisfy the requirements of miss distance and terminal angle, thus it guarantees that different parts of the large-airspace varying trajectory link smoothly. Guided by this guidance law an anti-warship missile realizes various forms of large-airspace varying trajectory. Adopting the large-airspace variable trajectory, an anti-warship missile can improve its maneuverability and penetration ability. The simulation results show the effectiveness of the proposed extended proportional navigation guidance law based on Lyapunov stability.
