An apparatus for measuring a range based on a chaotic ultra wideband (UWB) wireless communication technology is disclosed. The Apparatus includes a chaotic signal generating/modulating unit, a transceiving unit, a detecting unit, a transform unit, a comparison unit, and a range measurement unit. The transform unit converts the analog voltage signal from the detecting unit into digital signals based on a first sampling period. The comparison unit compares the analog voltage signal from the detecting unit with a predetermined threshold value and to output a comparison signal. The range measurement unit is configured to calculate a time point corresponding to a leading edge, which is a moment when initial data of a packet payload arrive, by using the digital signals based on the threshold value and by using the comparison signal, and to perform a range measurement calculation based on the time point corresponding to the leading edge. |
