Distance measuring method, distance measuring apparatus to which the distance measuring method is applied, and distance measuring equipment to which the distance measuring apparatus is applied

摘要

The amplitude of a standing wave (S) is detected, while performing variable frequency control of the transmitted signal. The distance from the measurement object (M) to the detection point and relative velocity of the measurement object are calculated simultaneously, based on the calculated signal corresponding to the amplitude of the standing wave. Independent claims are also included for the following: (1) a distance measuring device; and (2) a distance measurement installation.
