UWB DISTANCE MEASUREMENT SYSTEM AND A DRIVING METHOD THEREOF, CAPABLE OF IMPROVING NBI(NARROW BAND INTERFERENCE) IN AN UWB(ULTRA-WIDEBAND)

摘要

PURPOSE: A UWB distance measurement system and a driving method thereof are provided to reduce a negative element such as interference and noise by securing an NBI suppressing ability.;CONSTITUTION: In a UWB distance measurement system and a driving method thereof, an RX-antenna(20) receives a signal outputted from a transmission unit. An output signal of the transmission unit is reflected from a target object, and the UWB Amp generates a first signals by amplifying the signal received from the RX-antenna. A reference waveform generator generates a reference waveform by analyzing the first signals. A window function generator(40) generates a series of window function added to the reference waveform and the first signals of the reference waveform generator. A correlator generates the second signal by correlating the window function and the first signals from the UWB Amp.;COPYRIGHT KIPO 2010
