In this paper the problem how to estimate the time-of-flight of a received acoustic tone burst is addressed. In indoor applications, reflections cause interference patterns that are hardly predictable and can lead to large estimation errors. A generalisation of the well-known matched filter based on a non-stationary autocovariance model of the reflections allows us to develop a new estimator. Experiments show that the application of the new estimator can reduce these errors by about a factor four.
