This research presents a novel method for imaging objects hidden around corners by exploiting the scattering properties of THz waves. The researchers will modify the backpropagation SAR imaging algorithm to correct the cluttered 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. The research focuses on searching for various ideas that have been previously successfully implemented. This has a significant importance in surveillance applications. As the geometry considered for imaging is simple, the team will focus on working with complex imaging geometries.
