In this paper, the researchers present a review and classification of the published works on the use of Electromagnetic Time Reversal (EMTR)-based methods to locate landmines.
Different approaches for landmine localization using EMTR are investigated. Specifically, the classical time-domain EMTR, iterative EMTR, EMTR-DORT (Décomposition de l’Opérateur du Retournement Temporel), and EMTR-MUSIC (MUltiple SIgnal Classification) are implemented using different numerical techniques. The main properties of the mentioned EMTR-based approaches are reviewed and the TR-MUSIC method is selected as the most promising approach for the problem of interest, among all the reviewed methods.

- UK: AI-powered drones to detect explosive threats and protect military personnel
April 2, 2026
UK military personnel are set to be better protected on the battlefield as a result of trials which demonstrate cutting-edge AI in drones can rapidly recognise new threats, such as landmines and other explosive ordnance. The major trial by the Defence Science and Technology Laboratory (DSTL) on behalf of the British Army allowed bomb-disposal experts to ...
- Ukraine: How Drones and AI Are Helping Clear 36,000 Landmines
March 11, 2026
Four years after Russia’s invasion, Ukraine faces another crisis that will outlast the war itself: millions of landmines scattered across a thousand-kilometer front line, buried in some of the world’s best farmland. However, a remarkable transformation is underway. The HALO Trust, the world’s largest landmine clearance organization, has cleared over 36,000 explosives and returned 20 million ...
- Researchers are combining drones and AI to make removing land mines faster and safer
March 5, 2026
At least 57 nations have live antipersonnel land mines in their territories. In 2024 alone, 1,945 people were killed by mines and 4,325 were injured, 90% of whom were civilians. Nearly half of those were children. Demining operations removed 105,640 mines in the same year. With new conflicts, the number of mines continues to grow. The ...
- From landmines to algorithms: how Japan is helping Cambodia clear its war legacy
February 23, 2026
For more than three decades, landmines have remained one of Cambodia’s most painful legacies of war—hidden beneath rice fields, forest paths and village outskirts, long after the guns fell silent. Yet as the kingdom edges closer to its ambitious goal of becoming mine-free by 2030, one partnership stands out for both its longevity and quiet evolution: ...

- Detection and imaging of chemicals and hidden explosives using terahertz time-domain spectroscopy and deep learning
January 22, 2026
Detecting concealed chemicals and explosives remains a critical challenge in global security. Terahertz time-domain spectroscopy (THz-TDS) offers a promising non-invasive and stand-off detection technique owing to its ability to penetrate optically opaque materials without causing ionization damage. While many chemicals exhibit distinct spectral features in the terahertz range, conventional terahertz-based detection methods often struggle in real-world ...
