Abstract
The target-encirclement guidance problem for many-to-one missile-target engagement scenario is studied, where the missiles evenly distribute on a target-centered circle during the homing guidance. The proposed distributed target-encirclement guidance law can achieve simultaneous attack of multiple missiles in different line-of-sight directions. Firstly, the decentralization protocols of desired line-of-sight angles are constructed based on the information of neighboring missiles. Secondly, a biased proportional navigation guidance law that can arbitrarily designate the impact angle is cited. The missiles can achieve all-aspect attack on the target in an encirclement manner by combining the biased proportional navigation guidance law and dynamic virtual targets strategy. Thirdly, the consensus protocol of simultaneous attack is designed, which can guarantee that all missiles’ time-to-go estimates achieve consensus asymptotically, and the convergence of the closed-loop system is proved strictly via the Lyapunov stability theory. Finally, numerical simulation results demonstrate the performance and feasibility of the proposed distributed target-encirclement guidance law in different engagement situations.

With the rapid development of new and high-tech weapon equipment, the survivability of conventional missile attacker has been seriously weakened because of a variety of advanced defense systems such as antimissile defense system and close-in weapon system.[1,2] strenuous efforts have been made to develop a new high-performance missile attacker with terminal evasive maneuverability, hypersonic cruise capability, good stealth performance, or seaskimming flight capability despite a huge cost
For the n missiles subjected to an undirected and circularly connected communication graph G, the objective of this work is to design a distributed cooperative guidance law based on information from communication topology, so that the distributed target-encirclement simultaneous attack of multiple missiles can be realized
The proposed distributed target-encirclement guidance (DTEG) law can make the missiles evenly distribute on a target-centered circle when they are guided to the target and can ensure them arrive at the target simultaneously
Summary
With the rapid development of new and high-tech weapon equipment, the survivability of conventional missile attacker has been seriously weakened because of a variety of advanced defense systems such as antimissile defense system and close-in weapon system.[1,2] strenuous efforts have been made to develop a new high-performance missile attacker with terminal evasive maneuverability, hypersonic cruise capability, good stealth performance, or seaskimming flight capability despite a huge cost. For the n missiles subjected to an undirected and circularly connected communication graph G, the objective of this work is to design a distributed cooperative guidance law based on information from communication topology, so that the distributed target-encirclement simultaneous attack of multiple missiles can be realized. The target, such as an enemy’s warship, can be modeled as being stationary, because its velocity and maneuverability are not comparable to those of a missile at all.
