Distance measuring device and distance measuring method

Abstract

A distance measuring device includes: a communication processing unit that performs first radio communication using right-handed circularly polarized waves and second radio communication using left-handed circularly polarized waves as communication for distance measurement using a phase-based method with another device; and a distance measuring unit that measures a distance to the other device based on a first time waveform obtained by performing inverse Fourier transform on frequency characteristics of a signal transmission path obtained based on a received signal by the first radio communication and a second time waveform obtained by performing inverse Fourier transform on frequency characteristics of a signal transmission path obtained based on a received signal by the second radio communication.
