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.
摘要翻译：这里公开了使用窄带干扰抑制波形的超宽带（UWB）测距方法。发送信号被发送到目标对象。从目标对象反射的传输信号被接收。通过将窄带干扰抑制波形和信道估计信号组合在一起而产生模板信号。通过对模板信号和接收信号进行卷积生成相关输出信号。当相关输出信号具有最大值时，使用时间延迟来计算距离。窄带干扰抑制波形是由以下公式表示的两个波形中的任何一个：wr1（t）= g（t-δ1/ 2）+ g（t +δ1/ 2）wr2（t）= g δ2/ 2）-g（t +δ2/ 2）其中，g（t）是基本UWB脉冲波形，δ1=（N + 1/2）f1，δ2=（N）/ f1，N是整数， fi是窄带干扰信号的中心频率。
