Abstract

The terahertz (THz) spectrum, with its abundant available bandwidths, has garnered significant attention for its potential to advance wireless communications and enhance radar sensing capabilities, leading to improved data rates and spatial resolution, respectively. However, in indoor environments, the blockage or significant attenuation of THz waves due to the presence of humans and other obstructing materials poses a recognized challenge. Therefore, a line-of-sight (LoS) link is preferred though cannot be guaranteed in all situations. Nonetheless, this work explores the scattering properties of commonly encountered indoor objects, such as walls, for establishing a nonline-of-sight (N-LoS) link. An N-LoS testbed is employed to investigate both the communications and radar sensing capabilities through wall reflections. From a communications perspective, the recording of the transmit signal at varying incidence angles is presented. Additionally, radar imaging is demonstrated employing the syn-thetic aperture radar (SAR) technique, enabling the visualization of objects hidden from direct view.
