A novel THz radar imaging system using the radon transform

In this study a novel THz system is presented for 2D or 3D radar imaging. The system implements a Computerized Tomography's (CT's) algorithm that records the Radon Transform (RT) of an object and reconstructs the image using the Inverse Radon Transform (IRT). As such, the imaging system is comprised of a simple linear antenna that significantly simplifies the system topology and results in a compact and real-time imaging system. This configuration can be used for earth observation applications, standoff security monitoring and surveillance. In this work, the design of the novel THz imaging system is presented and simulation results of a phantom object at 300 GHz are verifying the proof of this concept.
