基于虚拟领弹-从弹的集群分布式协同制导技术研究

This paper investigates the problem of salvo attack guidance of multiple missiles and suggests a virtual leader-follower-based distributed cooperative guidance law to address this problem. The proposed guidance law is composed of two different parts: a baseline guidance law and an impact-time error feedback term. For scenarios with only impact-time constraint, the baseline guidance law is chosen as the classical pure proportional navigation for target capture. When considering both impact angle and impact time constraints, the well-known time-to-go weighted optimal guidance is leveraged as the baseline guidance law. Theoretical analysis reveals that the impact-time discrepancy among all missiles converges to zero at the time of impact. Finally, numerical analysis is conducted to demonstrate the effectiveness of the proposed algorithm.
