METHOD FOR DETECTING THE MOTION OF OBJECT BY ULTRA-WIDEBAND RADAR IMAGING AND SYSTEM THEREOF

摘要

A method for detecting the motion of object by ultra-wideband radar imaging and system thereof to be used to present the motion of object in a reference gray-level image by using the delay time to analyze the distance between the detected position of object and the detecting position to compare the time-varying distance variation between the reference distance and the detecting distance. The system includes a transmitter module, a receiver module and a signal processing module. The transmitter module is used to transmit a first ultra-wideband signal from a detecting position to the object. The receiver module is used to receive a second ultra-wideband signal reflected from the object in the detecting position. The signal processing module is used to analyze the signal delay time of the second ultra-wideband signal received in the detecting position to analyze the detecting distance between the second ultra-wideband signal and the detecting position.
