Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous
progress over the past 15 years. The development of GPR spans aspects of geophysical …

An ultrawide-bandwidth (UWB) ground penetrating radar (GPR) was used to collect fully-
polarimetric backscattered data from 10 to 800 MHz using a dual-polarization version of the …

We consider the detection of subsurface unexploded ordnance via magnetometer and
electromagnetic-induction (EMI) sensors. Detection performance is presented, using model …

Ground penetrating radar (GPR)-based discrimination of landmines from clutter is known to
be challenging due to the wide variability of possible clutter (eg, rocks, roots, and general …

The decomposition of the time reversal operator (DORT) method, originally developed in
acoustics, allows detection of scatterers embedded in the probed domain and provides …

A detailed analysis of ultrawide-band (UWB), dual-polarized, dielectric-loaded horn-fed bow-
tie (HFB) antennas is carried out using the finite-difference time-domain (FDTD) method. The …

This work introduces an efficient technique to design an electromagnetic target classifier
whose reference database is constructed using scattered data at only a few aspects. The …

The fast multipole method (FMM) was originally developed for perfect electric conductors
(PECs) in free space, through exploitation of the spectral properties of the free-space …

Battelle and The Ohio State University ElectroScience Laboratory have built and
demonstrated a ground-penetrating radar (GPR) system for locating buried unexploded …

Deeply buried inclusions such as pipes and cables cannot be detected when the air-ground
interface suffers severe impedance mismatch, resulting in little electromagnetic (EM) signals …
