Design constraints and error analysis of the temporal correlation log

The basic principles of spatial and of temporal correlation sonar for velocity measurement of both surface vessels and autonomous underwater vehicles are considered, showing the advantages of using a pulsed temporal correlation log. To achieve correlation, the conditions for waveform invariance must be met, and there is a velocity-depth limitation to be observed; these are described in detail. Practical design constraints such as the effects of different transducer sizes/geometry and carrier frequencies are also considered.<
