摘要：

This paper presents a noise immunity analysis of time delay estimation (TDE) techniques used on ultrasonic echoes for non invasive temperature estimation. Four methods are analyzed. The methodology consists on corrupting a simulated ultrasonic signal (ideal signal) with white noise and a signal-to-noise ratio of 3dB and 6dB. After this, noise immunity analysis is performed for every method. The TDE techniques used in this work are Phase Difference, Phase Shift, Cross-Correlation and Quadrature Phase Demodulation. The purpose of this work is to determine the best method for non invasive temperature estimation.
