Abstract :
The application of Doppler telemetry for velocity measurements of a free fall penetrometer is demonstrated and presented in this paper. The system design considerations and parameters are outlined together with the description of a prototype. Results from sea trials of the prototype are presented and its performance is evaluated. Possible modifications for the system are suggested.
