“…In addition, rough air-soil interface scatters GPR waves randomly, making the received data difficult to analyse, while when the antennas are in contact with the ground, the subsurface waveform is nearly unaffected by the roughness of the soil and therefore is easier to predict. As a consequence, data processing too is positively affected by a ground coupling survey [32], [33]. The ensemble of bistatic signatures has been collected by progressively shifting both the transmitter and the receiver away from the target location, known as Common Mid Point (CMP) acquisition.…”

With the proliferation of low-intensity conflict, landmines have proven to be one of the weapons of choice for both government and guerrilla forces around the world. Recent improvements to mine technology pose increasingly significant problems for demining operations, requiring the constant upgrading of countermine technologies. Ground Penetrating Radar (GPR) is one of the most exhaustively researched topics in the detection of buried mines as it can be used to detect non-metallic and plastic mines. However, identification and recognition are still unsolved problems, due to the scattering similarity between mines and clutter objects. This study provides an experimental evaluation of the improvements that a bistatic approach could yield and what can be gained from investigating the angular dependencies of the landmine radar signature.

“…Conversely, employing a ground coupled platform could greatly improve signal penetration and data resolution [35] [36]. When the antennas are in contact with the ground, the subsurface waveform is nearly unaffected by the roughness of the soil and therefore is predictable and easy to analyse, even for plastic landmines [37]. Figure 2 presents an example of the effects originated from elevating the antennas from the ground.…”

Ground Penetrating Radar (GPR) is widely recognised as an operationally useful sensor for mine detection as it can offer better detection performance than the ubiquitous metal detector in the presence of low-metal content mines. However, GPR has to overcome many potential sources of false alarm due to clutter and battlefield debris, which lower the efficiency of the sensor. This paper analyses a set of experimental data collected in a recent multi-offset GPR measurement campaign with inert landmines composed of different assemblies buried in sandy soil. The aim of the work is to evaluate the key differences observed by a radar system when the transmitter and the receiver are moved apart, as a function of their distance and hence when the illuminated section of the target is diversified. The results of the comparison between the collected multi-offset profiles show that using a bistatic geometry could represent a strategy to reconstruct composite objects with finer and better details.
