Subtle Detection of Target Profiles Using Submillimeter Waves

Continuously increasing interests and attentions for different applications in sub-MMW band (1000 to 100 mum ) have been received in recent years. Many unique applications of this electromagnetic spectrum have been demonstrated by pioneer researchers, such as in astronomical molecules detection and high resolution imaging. In this paper, we investigate the sub-MMW scattering properties of perfectly conducting objects. Based on the numerical study of radar cross sections for different targets with subtle features, we show that sub-MMW has the ability to capture the subtle target profiles.
