“…is based on the prevalent simplifications (Li et al, 2015) that (i) the Earth is a nonrotating uniform sphere, and (ii) the HGV's sideslip angle is negligible, leaving attitude and trajectory to be fully described by the angle of attack and bank angle. Furthermore, the commanded/desired acceleration is assumed to be zero (Hough, 2017;Cheng et al, 2020).…”

“…However, the absence of flight test data serving as ground truth poses two difficulties: (i) parameter values cannot be estimated from data, (ii) models cannot be validated. Academic researchers have been coping with these difficulties through parametric modelling, where a geometric model (Cheng et al, 2020) or aerodynamic model (Liu et al, 2018b) or manoeuvre model (Hu et al, 2021) is parameterised and subjected to simulations for the determination of suitable parameter values. For example,…”

“…6). • Cheng et al (2020) sampled the geometrical design space of HTV-2 to determine five possible geometrical configurations. For each of the five configurations, computational fluid dynamics simulations were (likely) used to calculate the values of three parameters, namely lift coefficients, drag coefficients and lift-to-drag ratio, for different angles of attack and Mach numbers.…”

“…For the evaluation of tracking filters, values for process noise, measurement noise and the initial error covariance matrix -when they are provided at all -generally require more rigorous justification and investigation. For example, these values are missing in (Cheng et al, 2020) and not justified in (Wang and Li, 2021).…”

Hypersonic vehicles are vehicles travelling faster than Mach 5 (five times the speed of sound). Hypersonic technologies have existed since the end of the 1950s, but recent developments of defence applications have led to their resurgence. Hypersonic weapons can be hypersonic (powered) cruise missiles or hypersonic glide vehicles (HGVs). The near-space trajectories of HGV, combined with their superior manoeuvrability, enable HGVs to evade existing space and terrestrial sensors used to track ballistic missiles, posing an immediate threat to today’s radar networks and making HGVs well-suited for intercontinental (> 5500 km) targets. Securing HGV detection and tracking systems is of great interest to at-risk nations and cybersecurity researchers alike. However, like hypersonic flight technologies, HGV defence technologies are heavily guarded secrets. The shortage of public-domain information did not stop academia from proposing various detection and tracking schemes, but a reasonable question is: “How credible and useful is current public-domain information, including academic publications, on HGV detection and tracking for academic researchers to base their cybersecurity research on?” To answer this question, we scanned and critically reviewed public-domain literature on HGV detection and tracking. We then identified ambiguities and knowledge gaps in the literature. In this paper, we provide a concise version of our multivocal literature review and an analysis of the identified ambiguities and knowledge gaps in our attempt to answer our earlier question.
