A distance measurement apparatus includes a calculation unit configured to calculate, based on phase information acquired by two distance measurement units at least one of which is movable, a distance between the two distance measurement units. One of the two distance measurement units includes an RSSI estimation unit configured to estimate, from respective three receiving signal intensities of three first carrier signals or respective three receiving signal intensities of three second carrier signals, the receiving signal intensity of a frequency having an average value, and a fading correction value calculation unit configured to calculate a fading correction value for the distance from the receiving signal intensity of a lowest frequency and the receiving signal intensity of a highest frequency. The calculation unit calculates the distance using a phase detection result obtained by receiving the three first carrier signals and the three second carrier signals and the fading correction value.
