Maneuver mode analysis and parametric modeling for hypersonic glide vehicles

The maneuver modes in the glide phase are explored from the perspective of hypersonic vehicle defense in this study, and a novel maneuver mode description approach is proposed. The longitudinal and lateral maneuver modes' mechanisms and evolution laws are explored. And, the focus of this research is on the evolution laws of complex lateral maneuver modes in real scenarios. To solve the maneuver mode description problems, a novel maneuver mode parametric analyzing and modeling method is proposed based on the Vector Auto-regressive model. Firstly, the Granger causality test is adopted to verify whether there are causal correlations between the maneuver characteristic parameter series, which have a high level of regularity and are taken as modeling variables. Then, the Vector Auto-regressive method is employed to model the coupling relationship between the maneuver characteristic parameters, as well as to provide a precise description method with simple structure and uniform form for various maneuver modes. Moreover, the model coefficients estimation and model order selection methods are presented. This study helps to deepen the understanding of the target's maneuver modes in hypersonic vehicle defense. Simulation results demonstrate that the proposed modeling method can greatly improve modeling accuracy. (C) 2021 Elsevier Masson SAS. All rights reserved.
