Curved Synthetic Aperture Radar for Near-Field Terahertz Imaging

High resolution imaging technique will play an essential role in the future smart applications to provide potential solutions for accurate detection, monitoring and classification of target. The synthetic aperture radar (SAR) systems acquire high images has opened new frontiers led its exploration applications. conventional microwave suffers limited range sub-millimeter wave optical methods are constrained by diffraction limit. In terahertz (THz) regime spectrum, SAR could be operated all weather, time capable penetrating through clouds, smoke, dust etc. achieve beyond curved presents a system created circularly encircling target scene. Circular Spiral which based on circular cylindrical spiral scanning trajectory, respectively used SAR. this paper, we have explored toolbox that enables rapid development near-field THz-SAR generation large THz scenarios with goal support facilitate data driven research such as deep learning community synthetically generated well 2D/3D application. Initially, advantages over Microwave presented. Further, frequency modulated continuous (FMCW) testbed is simulated multi-input multi-output (MIMO) configuration band. Moreover, point targets obtain 2D 3D images, respectively. Also, reconstructed using Back Propagation Polar Formatting Algorithms, focusing short like indoor environments. Finally, performance evaluation metrics reported roadmap work
