Title: Radio wave propagation distance estimation device
Inventor: KOGA KENICHI
IPC: G01S13/84
Filed: 2016-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a radio wave propagation distance estimation device that has made it possible to improve the accuracy of distance estimation.SOLUTION: A distance measurement signal derived by synthesizing N sinusoidal waves differing in frequency is transmitted from an onboard device 2 to a portable apparatus 3 by wireless, and the portable apparatus 3 returns it as it is and the onboard device 2 receives the distance measurement signal. An amount of phase rotation occurring between the distance measurement signal currently transmitted by the onboard device 2 and the distance measurement signal received by the onboard device 2 is obtained for each frequency, and a difference in the amount of phase rotation at frequencies adjacent to each other is further obtained. Since an inclination in the relationship between a frequency and a phase rotation amount indicates a delay time of the distance measurement signal, it is possible to calculate a propagation distance by multiplying the delay time by a known velocity of light and estimate the distance from the onboard device 2 to the portable apparatus 3. The distance measurement signals received by M antennas (equivalent to the onboard device 2) are synthesized by weighting in accordance with phase linearity and thereby the accuracy of distance estimation is heightened.SELECTED DRAWING: Figure 1
