Distributed Simultaneous Cooperative Guidance for Attacking a Maneuvering Target

In this paper, the cooperative guidance problem of simultaneous multi-missile attack on a maneuvering target is investigated. Firstly, a cooperative guidance model for multiple missiles is established, and an expression for estimating the time-to-go is provided. Moreover, a fixed-time nonlinear disturbance observer is designed to achieve the estimation of the target maneuver information online. Thirdly, a distributed simultaneous cooperative guidance law is developed, and the convergence of the cooperative guidance error is proven. Finally, numerical simulations are given to illustrate the effectiveness of the proposed cooperative guidance law.
