Guidance Law Based on Line-of-Sight Rate Information Considering Uncertain Modeled Dynamics

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 6, Page # 195–203, 2018; DOI: 10.25046/aj030626
Abstract:

Proportional navigation (PN) is a widely-used guidance law for missiletarget engagement. The goal of the missile intercept problem is to reduce the closest distance between the missile and target by diminishing the line-of-sight rate (LOS rate). In general, PN guidance law necessitates information of the LOS rate and missile velocity. The closing velocity (relative approaching…
