“…The declining cost of sensors [58] and rapid development of smaller commercial UAV technology [59] has enabled new approaches to the problem of landmine identification and clearing. To date, we have developed and field-tested a UAV-based thermal-imaging system that allows analysis of a 200 m 2 area in a single nine-minute flight and reliably locates any scattered PFM-1 landmines present within this area.…”

Use of landmines as a weapon of unconventional warfare rapidly increased in armed conflicts of the last century and some estimates suggest that least 100 million remain in place across post-conflict nations. Among munitions and explosives of concern (MECs), aerially deployed plastic anti-personnel mines are particularly challenging in terms of their detection and subsequent disposal. Detection and identification of MECs largely relies on the geophysical principles of magnetometry and electromagnetic-induction (EMI), which makes non-magnetic plastic MECs particularly difficult to detect and extremely dangerous to clear. In a recent study we demonstrated the potential of time-lapse thermal-imaging technology to detect unique thermal signatures associated with plastic MECs. Here, we present the results of a series of field trials demonstrating the viability of low-cost unmanned aerial vehicles (UAVs) equipped with infrared cameras to detect and identify the most notorious plastic landmines—the Soviet-era PFM-1 aerially deployed antipersonnel mine. We present results of an experiment simulating analysis of a full-scale ballistic PFM-1 minefield and demonstrate our ability to accurately detect and identify all elements associated with this type of deployment. We report significantly reduced time and equipment costs associated with the use of a UAV-mounted infrared system and anticipate its utility to both the scientific and non-governmental organization (NGO) community.

“…The status of these developments has been documented by suppliers [18][19][20][21][22], and the objectives of the work by a recent Army perspective [23]. Generally, 25-ìm pixel microbolometers are now achieving sensitivities comparable to those common for 50-ìm pixel devices of a few years ago.…”

Third generation sensors are under development to enhance capabilities for target detection and identification, threat warning, and 3D imaging. Distinct programs for both cooled HgCdTe and uncooled microbolometer devices are part of this thrust. This paper will describe the technology for HgCdle two-colour, high-definition imaging sensors and threat warning devices, avalanche photodiode arrays for 3D imaging, and the supporting technology being developed to enhance the readouts that support these devices. Uncooled detector initiatives will also be described to reduce pixel size in conjunction with the production of 480×640 arrays. Finally, efforts are also beginning to move both photon and thermal detectors closer to radiative-limited performance while simultaneously reducing the cooling requirements for photon detectors.
