This paper proposed an novel method for detecting echo signals.The wavelet function is used as the transmitted signal and the echo signal is detected with the corresponding completely same wavelet base.So the best match can be arrived.The advantage and implementation of new method was described.The simulation of the ultrasonic detection indicates the validity of the new way.The numerical results show good detection even for SNR of -17dB.Comparing with traditional method
the new method can increase the ability of signal detection.
