TL;DR: A novel data acquisition and imaging method is presented for stepped-frequency continuous-wave ground penetrating radars (SFCW GPRs) and it is shown that if the target space is sparse, it is enough to make measurements at only a small number of random frequencies to construct an image of thetarget space by solving a convex optimization problem which enforces sparsity through lscr 1 minimization.

TL;DR: In this paper, two antennas are considered, a cylindrical monopole and a conical monopole, which are driven through an image plane from a coaxial transmission line and analyzed by a straightforward application of the finite-difference-time-domain (FD-TD) method.

TL;DR: Bistatic and multistatic images for the buried targets are very good, and they show the effectiveness of the system and processing.

TL;DR: A novel data acquisition system for wideband synthetic aperture imaging based on CS by exploiting sparseness of point-like targets in the image space by using linear projections of the returned signals with random vectors as measurements.

TL;DR: A laboratory-scale experimental model has been developed and tested for a system that uses artificially generated high-frequency seismic waves in conjunction with a radar-based noncontact displacement sensor to detect buried landmines.
