The present invention relates to an impedance matching device comprising: a matching element array unit configured with a matching element array to which a transmission pulse and a received pulse pass, the transmission pulse being output from a system and the received pulse being the transmission pulse that is output to an outside and then reflected; an extraction/calculation unit extracting pulse information from the transmission pulse and the received pulse, calculating impedance values corresponding to the pulse information with respect to each of the transmission pulse and the received pulse, and calculating an impedance value having best response characteristics of the received pulse with respect to the transmission pulse as a matching impedance value; an array control unit routing the matching element array unit according to the matching impedance value; a first converter converting a frequency of the transmission pulse into a carrier frequency and outputting the transmission pulse having the carrier frequency to the matching element array unit; a second converter converting the carrier frequency output from the matching element array unit into a low frequency; and a converter control unit outputting a signal for controlling the frequency converting of the first converter and the second converter. |
