Abstract

We present analysis and some experiments for rapid recognition and detection of hidden objects (i.e. human figures) using terahertz radiation. T-rays have a unique advantage, namely high reflectivity compared with all other electromagnetic waves and the ability to pass through most building materials. Further, the high frequency range of the terahertz band has the potential of reduced equipment size as compared with current radar technology. Imaging, at these frequencies, is developing fairly rapidly as compared with communication. However, usual imaging in the form of SAR, ISAR or electro-optical imaging takes a long time due to the large dwell time to acquire a single image. In this report, we investigate techniques for rapid classification using one dimension high resolution range profiles. Methods of statistical pattern recognition will be applied for identification of the object.
