NEW SIGNAL PROCESSING METHOD OF TRANSIT TIME MEASUREMENT

Mathias J. Niemann

Abstract

The cross-correlation function is commonly used to measure the transit time between two similar signals. The maximum value of the cross-correlation function corresponds to the transit time. The other way to measure this is to add the two signals. This method is comparable with the well known interference measurement technique. In the spectrum of the added signals after filtering a cosine function can be determined. The frequency of this function is directly proportional to the transit time.
