Properties of range-only target motion analysis

摘要

In this paper, we address the problem of the range-only target motion analysis (RO-TMA) of a source whose velocity is constant when the trajectory of the observer is composed of two legs. By lack of room, we only illustrate the fact that the trajectory of the source is observable if and only if the bearings are constant. We end up with an apparent paradox: the Fisher information matrix (FIM) is singular if and only if the trajectory of the source is observable.
