Doppler ultrasound technique, was originally applied in the medical field and dates back more then 30 years. The use of pulsed emissions has extended this technique to other fields and has open the way to new measuring techniques in fluid dynamics.
In pulsed Doppler ultrasound, instead of emitting continuous ultrasonic waves, an emitter sends periodically a short ultrasonic burst and a receiver collects continuously echoes issues from targets that may be present in the path of the ultrasonic beam.....
