—This year, we have focused on the acceleration of two inverse operators, so that they can be used by the Compressive Sensing (CS) imaging algorithms in the future. In particular, the following activities were performed for this project: 1) Development of a multistatic FFT-based formulation for imaging applications; and 2) Acceleration of the multistatic… (More)
—This paper presents a novel norm-one-regularized, consensus-based imaging algorithm, based on the Alternating Direction Method of Multipliers (ADMM). This algorithm is capable of imaging composite dielectric and metallic targets by using limited amount of data. The distributed capabilities of the ADMM accelerates the convergence of the imaging. Recently, a… (More)
determining the dielectric constant of weak dielectric objects attached to the body. These improvements leads to faster, more accurate whole body imaging to improve the security screening process, with proved detection capabilities validated by means of measurements carried out with a first mm-wave portal prototype.
