摘要：
A new method of time delay estimation for ultrasonic echoes in noisy environment is proposed. By using the least mean square algorithm for adaptive line enhancer as a pre-filter and following by a cross correlator can achieve better performance than the conventional method. Computer simulations results confirm the superiority of the proposed method even at very low signal-to-noise ratios.
