DISTANCE MEASURING DEVICE, WATER LEVEL MEASUREMENT SYSTEM, AND DISTANCE MEASUREMENT METHOD

A distance measuring device includes one or more processors configured to: detect a wave formed by synthesizing a frequency-swept electromagnetic wave transmitted to an object with a wave reflected on the object; measure, based on the synthesized wave, a distance to the object; calculate a displacem...

Zusammenfassung:A distance measuring device includes one or more processors configured to: detect a wave formed by synthesizing a frequency-swept electromagnetic wave transmitted to an object with a wave reflected on the object; measure, based on the synthesized wave, a distance to the object; calculate a displacement-caused inclination, caused by the displacement of the object, of a power spectrum of the synthesized wave; and measure the distance based on a signal in which the displacement-caused inclination has been removed from the power spectrum.
