Document Type and Number:

WIPO Patent Application WO/2016/123734

Kind Code:

A1

Abstract:

Embodiments of the present disclosure relate to a method and device for echo signal processing and a level measurement system. In an embodiment of the present disclosure, the method comprises receiving an echo signal; delaying the received echo signal by N times of half period of the received echo signal, to obtain a delayed echo signal, wherein N is an integer; and multiplying the delayed echo signal with the received echo signal. With embodiments of the present disclosure, a simple but efficient echo signal processing solution can be provided, which could achieve a better signal to noise ratio without introducing any time delay.
