An effective imaging approach based on compressed sensing (CS) and fast iterative shrinkage-thresholding algorithm (FISTA) is proposed to realize the two-dimensional imaging in the single-input multiple-output (SIMO) radar system. In comparison with the traditional imaging method based on matched filtering, considerable simplification of the hardware structure would come true through the implementation...
Millimeter-waves are nonionizing, readily penetrate common clothing material, and are reflected from the human body and any concealed items. In this paper, a 3-D imaging system is proposed. It works in W-band in order to achieve high resolution. The image reconstruction algorithm used to form a focused image at near field is based on spatial frequency domain, and process of algorithm is displayed...
The single-input multiple-output (SIMO) array based imaging system has been applied for remote sensing and concealed weapon detection. In this paper, comparisons of the back-projection (BP) algorithm and wavenumber domain (wk) algorithm applied to SIMO imaging are provided both in the near-field case and far-field case. Simulations demonstrate that the BP algorithm performs better in the near-field...
Multimerization of peptides can improve the binding characteristics of the tracer by increasing local ligand concentration and decreasing dissociation kinetics. In this study, a new bombesin homodimer was developed based on an ε-aminocaproic acid-bombesin(7–14) (Aca-bombesin(7–14)) fragment, which has been studied for targeting the gastrin-releasing peptide receptor (GRPR) in prostate cancer. The...
