A major problem with forward-looking ground-penetrating radar (FLGPR) detection of buried explosive threats is the scattering from the rough ground surface. The authors have previously developed a real-time 3-D algorithm for single-view emulation of

Microwave nearfield imaging is useful for security applications as it safe, non-invasive and penetrates clothing. The phase details of the radar measurements are essential for reconstructing images of metal or dielectric objects which may be hidden o

Ground penetrating radar (GPR) is a viable tool for fast and high fidelity detection of concealed explosive threats. The radar effectiveness is limited by scattering from rough terrain which considerably obscures the buried target response. To calcul

Predictive 3D mm-wave nearfield radar modeling requires challenging tradeoffs between computational size and accuracy. For raster-scanned focused spot antenna systems, both the focusing array antenna and the target region must be finely and fully sam

Millimeter-wave imaging radar is becoming increasingly popular for sensing and security applications. Usually full phased arrays, synthetic apertures, or focusing reflect-arrays are employed to sense a given image space. One new approach is to genera

We present a novel non-iterative model based on ray analysis to characterize non-metallic, weak dielectric objects (like threat objects) on the surface of a highly conducting background (like the human body) using a focused continuous millimeter-wave

High bit-rate RF communication is shown to be possible in deep oil wells using the air gap between the steel cladding and exterior rock as a dielectric waveguide to propagate TE signals in the kHz to MHz range. Computational modeling analysis in both

The semianalytic mode matching (SAMM) algorithm is a quick and efficient computational method that models wave scattering from multiple objects in half-spaces. This algorithm re lies heavily on appropriate choices of coordinate scattering centers (CS
