Method for determining run time of ultrasonic pulse, involves transforming wavelet from separated ultrasonic pulse and reference pulse based on generated wavelet, and determining run time of ultrasonic pulse from wavelet transformation

摘要

The method involves determining a shape of a reference receiving pulse, transmitting an ultrasonic measuring pulse, and executing a measuring track. Receiving signals are received and scanned with a scanning rate. The ultrasonic pulse is searched in the receiving signals. The ultrasonic pulse is separated from the receiving signals. A wavelet is generated from the separated ultrasonic pulse. The wavelet is transformed from the separated ultrasonic pulse and the reference pulse based on the generated wavelet. A run time of the ultrasonic pulse is determined from the wavelet transformation. An independent claim is also included for a device for determining run time of an ultrasonic pulse.
