The two programs available for download on this page provide statistical estimates of the time-of-flight between signals. For the research at this facility, they have typically been used for shock and detonation wave data analysis, although there are likely to be more applications. These programs and their performance is discussed in a paper by Lu et al. (
doi:10.1016/j.ymssp.2008.11.001) for the journal
Mechanical Systems and Signal Processing. The program XCOR discussed in the paper has since gone through a few minor modifications. The program NCCC is different from XCOR in that it is an unbiased estimate. LabVIEW does not need to be installed to run NCCC.
