Consensus based Nonlinear Guidance for Cooperative Salvo

This work focuses on devising cooperative salvo guidance strategies to intercept both moving and stationary targets. Salvo attack aids in overcoming the disadvantages associated with one-to-one engagement, such as countering close-in-weapon systems. The proposed cooperative guidance strategy considers a nonlinear engagement dynamics as well as a time-to-go estimate that accounts for large heading errors, thereby circumventing the problems associated with linearized engagement dynamics. The cooperation among interceptors stems from their interactions over different topologies, leading to consensus in their time-to-go estimates, which ensures salvo attack. Simulations demonstrate the efficacy of the proposed guidance strategies for the various initial engagement conditions.
