Patent ID: 7782248

Claim:
An Ultra WideBand (UWB) distance measurement system using a linear chirp waveform, comprising: a reception antenna for receiving a signal, which is output from a transmission unit, is reflected from a target and is incident on the reception antenna; a UWB amplifier for amplifying the signal received from the reception antenna and generating a first signal; a reference waveform generator for generating a reference waveform which is a reference for analysis of the first signal; a window function generator for generating at least one window function that is applied to the first signal on a basis of the reference waveform output from the reference waveform generator; a correlator for correlating the first signal output from the UWB amplifier with the window function output from the window function generator, and generating a second signal which is a revised frequency response of the first signal; and a delay time detector for detecting a delay time component in the second signal output from the correlator.
