The Bearing-Only Target Motion Analysis (BOTMA) problem is to estimate the position and velocity of a target using bearing measurements. In this paper, we assume that the observer can access the inequality constraints imposed on target's speed, range, or target's course. For example, one constraint on a target's range is that it is upper bounded by the maximum sensing range of the observer. We introduce an inequality constrained TMA, which is to derive target states satisfying the constraints. We verify the e…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
