Abstract :
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.<>
