Direct Electronic Fourier Transforms (DEFT) for Camouflage Signature Measurement (CSM),

Abstract

The concept and technique is based on the Fourier transform of an image, and the method uses one of the most recent advances in surface acoustic wave (SAW) technology together with modern communications technology to obtain the camouflage signature measurement (CSM) of military objects. This SAW device produces an analog (RF) electrical signal containing the Fourier transform (including amplitude, frequency, and phase) of the spatial frequencies contained in a conventional image.
