Abstract:
A system and method of remote sound speed measurement are disclosed. In one embodiment, a system for estimating a sound speed comprises a plurality of transducers configured to i) transmit a first acoustic signal from a first location, ii) receive a first scattered signal at a second location, iii) receive a second scattered signal at a third location, and iv) receive a third scattered signal at a fourth location; and a microprocessor configured to i) estimate a travel time based on at least one of the first, second, or third scattered signals, ii) generate a cross-correlation signal comprising a product of at least two of the first, second, and third scattered signals, iii) estimate a travel time difference based on at least the cross-correlation signal, and iv) estimate a sound speed based on at least the estimated travel time and the estimated travel time difference.
