Abstract :
Several methods of increasing the signal-to-clutter ratio (SCR) of a pseudorandom ultrasound Doppler system are introduced, and a crosscorrelation function and a pair of pseudorandom sequences are derived. The authors also provide theory and experimental results for a Doppler flowmeter with a higher SCR based on this crosscorrelation method.<>
