  • Abstract
    Folkestad and Mylvaganam use a chirp technique to resolve an ambiguity in time-of-flight measurements. An alternative is to trigger an oscilloscope on one cycle of the initial tone burst, then vary the frequency. In the delayed burst, the correct cycle for time-of-flight measurements remains stationary.<>
