“…One of the main goals of present and future missions to Mars is the investigation of the subsurface of the planet by means of orbiting or landing Ground Penetrating Radars (GPR) [ Picardi et al , 2004; Seu et al , 2004; Berthelier et al , 2003; Leuschen et al , 2003; Grant et al , 2003; Vannaroni et al , 2004]. Such a technique seems to be particularly suitable to address some of the fundamental scientific queries of Mars history and evolution, like finding and locating water, mapping the stratigraphy of different areas (polar caps, sedimentary deposits, volcanic terrains, etc.…”

[1] In this paper a set of frequency domain (500 Hz to 1 MHz) experimental data on electrical and magnetic parameters of magnetite/silica mixtures as Martian soil simulants is presented. Complex permittivity was obtained by measuring the magnitude and phase of the electrical impedance of a capacitive cell filled with the tested material. Complex magnetic permeability was obtained by measuring the impedance of a toroid fully embedded in the mixtures. Both the permittivity and magnetic permeability exhibited an appreciable increase with the magnetite volume fraction and a complex behavior with grain size and origin. Furthermore, to assess the possibility of extending the data acquired at 1 MHz to higher frequencies (tens to hundreds of MHz), some comparisons were made between these data and Time Domain Reflectometry measurements. Finally, the attenuation versus magnetite volume fraction and frequency (in a band consistent with the MARSIS and SHARAD sounders) was computed for various types of magnetite/silica mixtures. The results indicate that in a dry soil which contains a significant fraction of magnetic material both the wave velocity and the attenuation are a combination of different factors, including the dimension, shape, and origin of the magnetic material.

“…The GPSAR was ineffectual on the clay lane failing to detect all the AT mines with a FAR greater than 1 Fa/m 2 at 75% Pd. This performance was expected as clay is known to be a difficult detection environment for GPSAR due to its electromagnetic properties [2] . Four AT mines and two bounding fragmentation mines were encountered during coverage of this lane.…”

The Nemesis detection system has been developed to provide an efficient and reliable unmanned, multi-sensor, groundbased platform to detect and mark landmines. The detection system consists of two detection sensor arrays: a Ground Penetrating Synthetic Aperture Radar (GPSAR) developed by Planning Systems, Inc. (PSI) and an electromagnetic induction (EMI) sensor array developed by Minelab Electronics, PTY. Limited. Under direction of the Night Vision and Electronic Sensors Directorate (NVESD), overseas testing was performed at Kampong Chhnang Test Center (KCTC), Cambodia, from May 12-30, 2008. Test objectives included: evaluation of detection performance, demonstration of real-time visualization and alarm generation, and evaluation of system operational efficiency. Testing was performed on five sensor test lanes, each consisting of a unique soil mixture and three off-road lanes which include curves, overgrowth, potholes, and non-uniform lane geometry. In this paper, we outline the test objectives, procedures, results, and lessons learned from overseas testing. We also describe the current state of the system, and plans for future enhancements and modifications including clutter rejection and feature-level fusion.

“…GPR is often employed for nondestructive testing close to a ground interface with the aim of localizing buried targets in the shallow subsurface, such as in landmine detection and other important civil, forensic, archaeological, geophysical, and planetary applications [1][2][3][4][5][6][7][8][9][10].…”

Abstract-The capability of Ground Penetrating Radar (GPR) systems of accurately reconstructing the geometrical features of buried objects when working in critical conditions is investigated. A customized microwave tomographic approach is used to tackle the imaging through the processing of comparative experimental and synthetic GPR data. The first ones have been gathered in laboratory controlled conditions, while the second ones have been obtained by exploiting an ad-hoc implementation of a CAD tool. Attention is paid to the significant case of 'strong' scatterers having size comparable to the wavelengths of the probing signal, and possibly located close to the interface where the GPR antennas move. The results from imaging point out the potential of the proposed approach, showing in particular to which extent in challenging operational settings, it is possible to recover also the information about the shape of metallic targets in addition to their correct location and size.
