“…1 GPR has been used in explosive hazard avoidance roles since at least the 1970s. 2 First employed as a vehiclemounted sensor for in-route landmine detection, 3,4 advances in the technology have allowed for the development of hand-held versions, 5 where it is often paired with an electromagnetic induction-based (EMI) sensor.…”

The Canadian Armed Forces (CAF) identified a requirement for inert simulants to act as improvised, or homemade, explosives (IEs) when training on, or evaluating, ground penetrating radar (GPR) systems commonly used in the detection of buried landmines and improvised explosive devices (IEDs). In response, Defence R&D Canada (DRDC) initiated a project to develop IE simulant formulations using commonly available inert materials. These simulants are intended to approximate the expected GPR response of common ammonium nitrate-based IEs, in particular ammonium nitrate/fuel oil (ANFO) and ammonium nitrate/aluminum (ANAl). The complex permittivity over the range of electromagnetic frequencies relevant to standard GPR systems was measured for bulk quantities of these three IEs that had been fabricated at DRDC Suffield Research Centre. Following these measurements, published literature was examined to find benign materials with both a similar complex permittivity, as well as other physical properties deemed desirable -such as low-toxicity, thermal stability, and commercial availability -in order to select candidates for subsequent simulant formulation. Suitable simulant formulations were identified for ANFO, with resulting complex permittivities measured to be within acceptable limits of target values. These IE formulations will now undergo end-user trials with CAF operators in order to confirm their utility. Investigations into ANAl simulants continues. This progress report outlines the development program, simulant design, and current validation results.

“…Spectrum with no mine is also shown (blue lower curve). 1 For the landmine scenario, very few environmental gamma rays are present in the nitrogen ROI ð$9:5211:1 MeVÞ, due to low isotopic abundance, low capture cross-sections or both. Although the 10.607 MeV line from thermal neutron capture on 29 Si can be marginally visible at low source strengths [9], comparisons of spectra for low-and high-strength sources have shown [3] that the pile-up spectrum dwarfs any silicon contribution at the source strengths used in the operational TNA.…”

“…There is also a steeply sloped background component in the window, due primarily to residual pulse pile-up that is passed by the pileup rejectors. 1 To allow reliable detection of nitrogen at a high confidence level in less than a few minutes, accurate and repeatable energy calibration and background compensation are essential. Because the nitrogen lines cannot be resolved, nitrogen must be detected by subtracting counts in the ROI for a spectrum where bulk nitrogen is not present (''background spectrum'') from counts in the ROI for a spectrum taken over the target of interest (''target spectrum'').…”

“…To date, various prototype multisensor mine detector systems have been developed. As an example Canadian teleoperated landmine detection systems use five different technologies: electromagnetic induction, visible wavelength imaging, GPR for a quick scan of the minefield and thermal neutron analysis as a confirmation tool [2] [3]. The combination of GPR and metal detector was discussed in [4] [5].…”

Abstract-A next generation system, as an upgrade of a robotic mobile system for anti-personnel landmine clearance, was considered. In contrast to the first generation system where the fast neutron activation method and the associated alpha particle imaging (API) was supposed to be used for finding the residual explosives and/or landmines, in the next generation system fast neutrons (FN) was considered to be used only for the confirmation of the explosive in the suspected object previously found by the ground penetrating radar (GPR), metal detector (MD) and infrared imaging (IR). Such system is expected to have the acceptable price and the optimal demining vehicle speed of 10 cm/s. In contrast to the previous system only one neutron generator (NG) is needed. In order to study the possibility of FN to confirm the presence of TNT explosive in the real environment the tests were made with the soil of different moisture contents. Comparative study was done by using the cm cm BGO, cm cm and cm cm NaI(Tl) gamma-ray detectors. Although nitrogen was easily detected in larger amount of TNT explosive, its signal was weak in detection of Anti-Personal (AP) mine like DLM2.4. The presences of soil additionally diminish the possibility of nitrogen detection even in the Anti-Tank mines (AT).Index Terms-Antipersonnel landmine detection, associated particle imaging, fast neutrons, multisensor.
