The Role of Coherence in Time Delay Estimation A Paper Presented at the NATO Advanced Study Institute, LaSpezia,Italy 30August - 11September 1976.

摘要

This paper investigated methods for passive estimation of the bearing to a slowly moving acoustically radiating source. The mathematics for the solution to such a problem is analogous to estimating the time delay (or group delay) between two time series. Since the estimation of time delay is intimately related to the coherence between two time series, a summary of the properties of coherence is presented. (Author)
