Terahertz (THz) Synthetic Aperture Radar (SAR) is an emerging technology capable of generating a high-resolution map of the environment. SAR integration with unmanned aerial vehicles (UAVs) or mobile robots enables promising applications such as indoor/outdoor THz environment map, incorporating high-resolution imaging and localization, surface profiling and material characterization. The aforementioned applications must be executed in real-time, making it essential to propose a computing platform that can accelerate these applications effectively. This paper presents a roadmap towards realizing a computing platform for real-time material mapping utilizing THz SAR. In this paper, we present the state-of-the-art of our novel computing architecture and methodology for material map generation.
