Abstract

We present a novel method for imaging objects hidden around corners by exploiting the scattering properties of THz waves. Most common building materials have significant specular reflection components that enable THz imaging systems to see around occlusions. Additionally, such materials scatter incident waves to multiple directions which we can use to distinguish between the reflective surfaces and the object of interest. We modify the backpropagation SAR imaging algorithm to correct the clu t-tered raw data and acquire accurate THz images of the occluded areas. The new imaging approach is verified through imaging examples in the 220-330 GHz band using common building materials as mirrors.
