Abstract
A new digital hardware has been developed to measure the snow depth using ultrasonic sensors. The snow depth is measured with the new hardware. The reflected ultrasonic waveform from the snow surface is analyzed. The conventional TOF measurement with threshold is shown to be not adequate to derive the snow depth. The nonlinear least square method is shown to be effective for the outdoor environment.
