摘要： PROBLEM TO BE SOLVED: To provide a stationary wave distance sensor which can measure the distance to an object to be measured when it is in the stationary state and estimate a position at which the object to be measured will arrive after a lapse of predetermined time when it is on the move stably and with high precision.
SOLUTION: The stationary wave distance sensor comprises a transmitter for transmitting a transmission wave while sweeping the frequency of the transmission wave and a detection means for detecting the amplitude intensity of a stationary wave formed between the transmitter and the object to be measured, measuring the distance from the transmitter to the object to be measured. The transmitter sweeps the frequency of the transmission wave. A distance estimation means is provided which converts the relationship of the amplitude intensity of the stationary wave with the swept frequency into the relationship of the amplitude intensity of the stationary wave with a distance detected by the Fourier transform and estimates that a distance corresponding to a peak of the amplitude intensity of the stationary wave is a distance from the transmitter to the position at which the object to be measured will arrive after a lapse of predetermined time.

摘要： PROBLEM TO BE SOLVED: To provide a distance measuring device, a distance measuring method, and a distance measuring program capable of measuring accurately to a near distance even in a narrow radiation frequency band.
SOLUTION: A transmission part 20 emits an electromagnetic wave having the same frequency as an output signal from a dispatch part 12 in the measuring axis (x-axis) direction. A detection part 30 detects synchronously a reflected wave R detected by a directional coupler 32 by an in-phase signal and an orthogonal signal of a transmission signal, and extracts a direct-current component from the detected signal, to thereby detect an in-phase component I(f) and an orthogonal component Q(f) of the reflected wave R. An analysis signal generation part 42 mixes the in-phase component I(f) and the orthogonal component Q(f) of the reflected wave R with signals I
0 (f), Q
0 (f) having periodicity corresponding to a prescribed distance d
0 , and generates an analysis signal p(f) by using only one of acquired sideband waves. A Fourier transform part 44 determines the distance to a measuring object by a profile P(x) acquired by subjecting the analysis signal p(f) to Fourier transform.
