Design Strategy Of Snow Depth Sensor Based On Ultrasonic Pulse-Transit Technique For Remote Measurement Of Snow Cover Thickness, Raman Attri
Raman K. Attri
Snow cover thickness is one of the important parameter used in forecasting models for snow-melt, snow run-off water, snow avalanche release and other snow hydrological changes. Ultrasonic pulse transit method is being used for such applications universally. Reflected echo coming after reflection from highly irregular and non-smooth porous surface, is very low amplitude noise ridden signal. This received echo signal has to be conditioned to remove signal and processed to increase its amplitude to make it sufficiently detectable and to increase the probability of receiving back the reflected echo. A special design of Snow Depth Sensor based on Ultrasonic Pulse …
