Abstract
An angle calculation device according to the present technology includes an angle calculator that calculates, based on receipt signals of each of two or more first antennae and a second antenna, an angle of arrival of a radio wave at the first antennae from the second antenna. The first antennae are disposed in a first device at a spacing of a 0.25 wavelength or less of a carrier wave. The second antenna is disposed in a second device different from the first device. The receipt signals are obtained by performing round-trip communication for phase-based ranging between the first antennae and the second antenna.
