Notice of Violation of IEEE Publication Principles An impact-time-control guidance law for multi-missiles

The impact time control law is employed to carry out a salvo attack for anti-ship missiles against CIWS (close-in weapon system). An impact-time-control cooperative guidance law for multi-missiles was investigated in this paper. Firstly, the time-to-go for each missile was estimated and based on which the desired impact time was determined, and the impact time control problem was transformed into a range tracking problem. Secondly, a nonlinear model for homing guidance was proposed, which was transformed into a linear system by using feedback linearization. Lastly, a stable control law was designed by using pole placement approach. Simulation results show that all missiles can impact the target at the designated impact time very accurately.
