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 3 dB and 6 dB. 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.
