ABSTRACT:
A distance measuring method simultaneously measures a distance between a distance measurement system (10A) and a measurement object (M), and a relative speed therebetween. In the method, the distance measurement system sends an electromagnetic wave toward the measurement object as a traveling wave while changing a frequency thereof. The measurement object reflects the traveling wave to produce a reflected wave. The traveling wave and the reflected wave interfere with each other to produce a standing wave. The distance measurement system detects the amplitude of the standing wave and produces an amplitude signal representing the amplitude of the standing wave. Based on the produced amplitude signal, the distance measuring system derives the distance and the relative speed between the distance measurement system and the measurement object.
