Abstract
A technique for use in security screening and detection contexts employs an X-ray explosive imager that acquires images from backscattered RF modulated X-ray signals on which a time series analysis is performed to detect image change across the time series of images that represent pixels changing at the rate of the difference frequency of the RF frequency and the a priori NQR signature frequencies.
