摘要
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−δ1/2)+g(t+δ1/2); wr2(t)=g(t−δ2/2)−g(t+δ2/2);where g(t) is a basic UWB pulse waveform, δ1=(N+1/2)f1, δ2=(N)/f1, N is an integer, and fi is the center frequency of a narrowband interference signal.
