RF Tomography for Below-Ground Imaging of Extended Areas and Close-in Sensing
(Institute of Electrical and Electronics Engineers, 2010-07-01)
Three extensions to radio-frequency (RF) tomography for imaging of voids under wide areas of regard are presented. These extensions are motivated by three challenges. One challenge is the lateral wave, which propagates ...
Imaging Below Irregular Terrain Using RF Tomography
(Institute of Electrical and Electronics Engineers, 2012-09)
Radio-frequency (RF) tomography is extended for imaging underground structures and tunnels assuming rough terrain. The theory of RF tomography described in an earlier paper remains applicable, provided that a numerical ...
Tunnel detection and localisation via multi-monostatic radio frequency tomography using magnetic sources
(The Instution of Engineering and Technology, 2012-11)
An inverse scattering approach is presented to detect, localise and estimate the geometry of buried dielectric targets, in a 2D scenario, by exploiting magnetic sources as transmitting antennas. Explicit formulas to compute ...
Radio Frequency Tomography for Tunnel Detection
(Institute of Electrical and Electronics Engineers, 2010-03)
Radio frequency (RF) tomography is proposed to detect underground voids, such as tunnels or caches, over relatively wide areas of regard. The RF tomography approach requires a set of low-cost transmitters and receivers ...
