Abstract

A position determination method including a step of transmitting a periodic signal having a carrier frequency, a step of sequentially receiving the periodic signal having the carrier frequency at various locations using at least one antenna, and a step of determining a first coordinate of the object location on the basis of a zero crossing of a Doppler frequency response which may be associated with the first coordinate of the object location, the first coordinate of the object location corresponding to a coordinate of that location of the at least one antenna which it has when receiving the periodic signal at the zero crossing in relation to the object location.
