      • Abstract
    • Aimed at the ultrasonic signal polluted by noises, which is low in SNR, a method of the ultrasonic signal denoising in wavelet domain based on an improved threshold function was put forward. By the simulated test, this method was showed a remarkable effect in signal denoising. Compared with the traditional threshold functions, the improved one was more advantageous in ultrasonic signal denoising.
