Abstract
Embodiments relate to a speed sensor and a speed sensing method for measuring relative speeds of receivers with respect to particles in a fluid by detecting individual particles. A receiver generates a plurality of signals related to reflections from particles in a region being monitored. A sampling circuit samples the signals, and a processing device processes the signals according to a particle detection scheme to determine speed. Concomitant use of the same receivers allows depth measurement.
