Abstract
A method of determining a distance from an object performed in an apparatus including a radar, the method including receiving a reflection signal produced by a transmission signal reflecting from the object, the transmission signal being modulated by a default code sequence; converting the reflection signal into a reflection code sequence; generating a subject correlation vector including at least one correlation between at least one assistance code sequence and the reflection code sequence; and determining a distance corresponding to the subject correlation vector by referencing a lookup table storing at least one reference correlation vector including at least one correlation between the at least one assistance code sequence and the default code sequence.
