Time-delay estimation is a key parameter in passive acoustic positioning; whose accuracy directly affects the positioning accuracy. In this paper, focused on the basic theory of time delay estimation and the system design, the ROT H cross-correlation of pairs of collected sound signals was adopted. The results prove that the arithmetic can effectively extract the time delay values from complex acoustic signals.
Key words： time delay estimation; DSP; signal acquisition
