Abstract: Disclosed herein is an Ultra-WideBand (UWB) ranging method using a narrowband interference suppression waveform. A transmission signal is transmitted to a target object. The transmission signal, reflected from the target object, is received. A template signal is generated by combining the narrowband interference suppression waveform and a channel estimation signal together. A correlation output signal is generated by convoluting the template signal and the received signal. A distance is calculated using a time delay when the correlation output signal has the maximum value thereof. The narrowband interference suppression waveform is any one of two waveforms that are expressed by the following Equation: wr1(t)=g(t??1/2)+g(t+?1/2) wr2(t)=g(t??2/2)?g(t+?2/2) where g(t) is a basic UWB pulse waveform, ?1=(N+1/2)f1, ?2=(N)/f1, N is an integer, and fi is the center frequency of a narrowband interference signal.
