“…In practice, (1)-(3) can be realized using: 1) migration techniques in the spatial domain [6], [7] or 2) plane-to-plane propagation [38]- [41]. In a uniform medium, the radar return time delay from transmitter at (x, y T , z A ) to point scatterer at (x, y s , z s ) back to the colocated receiver at (x, y T , z A ) (all of which lie in the same vertical yz plane) is twice the travel distance from transmitter to point scatterer divided by the radar propagation velocity in that medium.…”

The focus of this paper is an empirical study conducted to determine how imaging modes for ground penetrating radar (GPR) affect buried object detection performance. GPR data were collected repeatedly over lanes whose buried objects were mostly nonmetallic. This data were collected and processed with a GPR antenna array, system hardware, and processing software developed by the authors and their colleagues. The system enables GPR data to be collected, imaged, and processed in realtime on a moving vehicle. The images are focused by applying multistatic and synthetic aperture imaging techniques either separately or jointly to signal scans acquired by the GPR antenna array. An image-based detection statistic derived from the ratio of buried object energy in the foreground to energy of soil in the background is proposed. Detection-false alarm performance improved significantly when the detection algorithm was applied to focused multistatic synthetic aperture radar (SAR) images rather than to unfocused GPR signal scans.Index Terms-Ground penetrating radar (GPR), multistatic imaging, synthetic aperture radar (SAR).

In this work is studied the microwave imaging using an (Ultra-Wideband) UWB antenna, for detection of lesions in tissues as an alternative for the use of X-ray. This paper describes the necessary procedure to realize the target (tumor) detection using microwave imaging. Despite the difference in the materials of the target and the surrounding medium, the procedure is the same as that used for phantoms that mimics the tissue and tumor. To simplify the understanding of the procedure, the target is a metallic sphere and the environment is the air. The Kirchhoff migration algorithm was implemented for the image reconstruction.

The focusing capabilities for one dimensional (ID-CR MIMO) and two dimensional circularly rotating multiple input multiple output (2D-CR-MIMO) arrays in different media are investigated. Impact of the position of the focusing point on the beamwidth and sidelobe structure is investigated. Impact of the medium (dielectric permittivity and ohmic losses) on the focusing capabilities is studied. For focusing point located at the edge position, within non or low conductive media, the -3 dB main beam width for both arrays become wider. In the same media, the form of the side lobes for 2D-CR MIMO array exhibit a spreading form while those for ID-CR MIMO array show a spreading and periodic form. Within the high conductive medium, side lobes are concentrated around virtual elements which have a relatively narrow geometrical angle to the focusing point.
