Coded signals received by a moving receiver or from a moving source exhibit a time‐scaling Doppler effect that can be detrimental to their ability to be correctly decoded. The effect is especially critical for the highly Doppler sensitive pseudo‐random noiseMsequences frequently used to measure propagation travel times. This paper develops a technique to measure dynamic Doppler effects empirically by tracking the phase of the transmitted carrier, and to remove such effects through interpolation and resampling of the signal. These techniques were very effective for simulated signals and will in the future be employed to help resolve the propagation times of the Heard Island feasibility test data collected by the Canadian receivers.
