文摘
- •
An applicable method is proposed for accurate ultrasound speed measurement.
- •
Noise and echoes are suppressed effectively by using MLS-modulated CW.
- •
Inherent delays and path length are corrected through least square estimation.
- •
Standard deviation of ultrasound speed measurement is less than 0.003 m/s.
- •
Deviation between measured ultrasound speed and reference is less than 0.04 m/s.
