The Realization of the Millimeter Wave Imaging System Based on Vector Network Analyzer

Abstract

Using the vector network analyzer hand spread spectrum module, the attenuation characteristics of THz wave near the 75 GHZ to 110 GHZ(W), the characteristics or internal defects of the object can be imaged, through the reflected and transmitted treatment. The use of Matlab platform to study and analysis on a variety of imaging algorithm and the image processing, feature selection for object accurate imaging algorithm, realize high-resolution images show that efficient internal defect coal imaging information.
