The estimation of the time-of-arrival (TOA) and/or time-of-flight (TOF) of the ultrasonic echoes is essential in ultrasonic non-destructive evaluation. In this paper, a sparse deconvolution method is proposed for deconvolving ultrasonic signals. To obtain the transducer pulse-echo wavelet, matching
