“…The microwave based UWB SAR have also been reported to be suitable for imaging sensing applications in monitoring oil reservoir, wall imaging, material characterization, geo mapping, weather forecasting and tissue imaging [31]. The application of radar based microwave imaging for breast cancer detection has been also investigated in [32] where the matching pursuit algorithm (MPA) has been applied to reconstruct scattering map of the breast from the monostatic Inverse Synthetic Aperture Radar (ISAR) imaging.…”

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

In this article, the approach based on the inverse circular radon transform technique (ICRT) is proposed to obtain the image of the breast cancer screening based on microwaves. A simplified numerical breast model is constructed and computational results are obtained with the use of synthetic aperture radar principle. A tumor phantom is produced and the experimental results are acquired by using sand, screw and phantoms with the use of an experimental setup prototype that is also presented in this study. The simulation results are verified and validated by experimental results. The resultant images generated using the simulated and experimental data show a good agreement with the designed scenarios.

“…In nondestructive testing, like assessment of the deterioration of concrete structures, circular ISAR is mostly exploited to achieve high resolution maps of the material defects (Hong, et al 2000). In security applications such as imaging of concealed objects (Detlefsen, et al 2005, Bertl, et al 2007, Bertl, et al 2008, Bertl, et al 2010and Sheen, et al 2010, a circular SAR or ISAR scanning is frequently used to obtain different views of the human body as well as in biomedical applications such as detection of tumors (Naseri, 2015, Avsar, et al 2016, Bicer, et al 2018and Celik, et al 2019.…”

Inverse synthetic aperture radar (ISAR) imaging is a reliable detection and classification technique for maneuvering targets at near and far-field ranges. In this study, we examine the near-field circular (turntable) ISAR imaging by conducting various real measurement experiments that were performed in the microwave anechoic chamber of the Mersin University's MEATRC laboratory. The backscattered data were collected via a vector network analyzer that works as a Stepped Frequency Continuous Wave (SFCW) radar and for a number of simple and complex metal objects. The collected raw data were calibrated by using the backscattering data of a canonical object and then focused by applying a near-field backprojection image reconstruction algorithm. The resultant circular ISAR images demonstrate successful and well localized detection of various types of targets even though they are camouflaged by clothing. The obtained results reveal the preliminary efficacy of C band ISAR imaging in concealed object detection problem encountered at security checkpoints such as airports.
