Locating signals by linking auto-and cross-correlation functions in the time domain

Abstract -
Cross-correlation does not allow one to estimate differences in travel time of the first arrivals at two receivers when multipaths lead to larger peaks than that due to the first arrivals. When the peaks in the cross-correlation function have high signal-to-noise ratios, a new algorithm is shown to correctly identify the desired peak in the cross-correlation function. The algorithm is based on additional information in auto-correlation functions. The algorithm has application to locating calling animals with widely distributed receivers.
