Paper Abstract

Recently, there has been a significant interest in employing Terahertz (THz) technology, spectroscopy and imaging for standoff detection. The main advantage of terahertz systems is the possibility for remote detect and identification of chemical compounds. Practical security system in reflection mode is desired. Unfortunately, reflection spectra for many compounds are very similar. Therefore, the simple correlation method is not sufficient to distinguish substances. In this paper we present the concept of using combined techniques of Short Time Fourier Transform (SFFT) and image processing with pattern recognition application in the area of automatic identification of explosives in THz range.
