Co-operative 3D salvo attack of multiple missiles under switching topologies subject to time-varying communication delays

Abstract

This study focuses on the co-operative salvo attack problem of multiple missiles against a stationary target under jointly connected switching topologies subject to time-varying communication delays. By carefully exploring certain features of the typical pure proportional navigation guidance law, a two-stage distributed guidance scheme is proposed without any information on time-to-go in this study to realise the simultaneous attack of multiple missiles. In the first guidance stage, a co-operative guidance law is proposed using local neighbouring communications only to achieve consensus on range-to-go and heading error to provide favourable initial conditions for the latter phase, in which switching topologies and time-varying communication delays are taken into account when obtaining sufficient conditions of consensus in terms of linear matrix inequalities. Then, missiles disconnect from each other and are guided individually by the typical pure proportional navigation guidance law with the same navigation gain to realise salvo attack in the second guidance phase. Finally, numerical simulations are carried out to clearly validate the theoretical results.

Recent progress on the study of multi‐vehicle coordination in cooperative attack and defense: An overview

“…Following the two‐stage guidance design approach introduced in Section 3.1.2, 3‐D cooperative guidance law against stationary target is developed [8], and convergence analysis considering fixed communication delay is conducted. This result is further extended to 3‐D guidance design for simultaneous attack under jointly connected graphs and uniform time‐varying communication delay in Ai et al [37]. Using the range‐to‐go‐based design approach, the problem of simultaneous attacks against maneuvering targets is further studied under communication delays in Liu et al [38] and under input delays in Li et al [39].…”

“…The problem of three-dimensional simultaneous attacks under communication delays is investigated in other works [8,37,38]. Following the two-stage guidance design approach introduced in Section 3.1.2, 3-D cooperative guidance law against stationary target is developed [8], and convergence analysis considering fixed communication delay is conducted.…”
