Query: Echo-enabled Direction-of-Arrival and range estimation of a mobile
  source in Ambisonic domain   Range estimation of a far field sound source in a reverberant environment is
known to be a notoriously difficult problem, hence most localization methods
are only capable of estimating the source's Direction-of-Arrival (DoA). In an
earlier work, we have demonstrated that, under certain restrictive acoustic
conditions and given the orientation of a reflecting surface, one can exploit
the dominant acoustic reflection to evaluate the DoA \emph{and} the distance to
a static sound source in Ambisonic domain. In this article, we leverage the
recently presented Generalized Time-domain Velocity Vector (GTVV)
representation to estimate these quantities for a moving sound source without
an a priori knowledge of reflectors' orientations. We show that the
trajectories of a moving source and the corresponding reflections are spatially
and temporally related, which can be used to infer the absolute delay of the
propagating source signal and, therefore, approximate the microphone-to-source
distance. Experiments on real sound data confirm the validity of the proposed
approach.
