Wildlife crime is an international issue with the illicit trade of flora and fauna estimated to be worth several billion dollars. In national parks, the problem can often be summarised as an arms race, with poachers trying to remain undetected by park rangers and other security personnel that are trying to protect the natural habitat and species from exploitation. Within this context, the detection of wire snares is a critical step. Not only can it reduce the number of animals caught by poachers but it can also help rangers develop better situation awareness and, in turn, improve patrolling strategies. To address the practical challenge of wire-snare detection across wide areas, this article examines the capacity of ground penetrating radar (GPR). Using two snares of small and medium sizes, the experiment confirmed the promising role of this technology, even if poachers attempt to conceal the snares underneath small tree branches and roots.

利用探地雷达探测金属线痕的可行性的实验评估

野生动植物犯罪是一个国际问题，动植物的非法贸易估计价值数十亿美元。在国家公园中，问题通常可以概括为军备竞赛，偷猎者试图使公园护林员和其他试图保护自然栖息地和物种免遭剥削的安全人员保持不被发现。在这种情况下，钢丝圈套的检测是至关重要的一步。它不仅可以减少偷猎者捕获的动物数量，还可以帮助护林员更好地了解情况，进而改善巡逻策略。为了解决跨大区域的线虫探测的实际挑战，本文研究了探地雷达（GPR）的能力。使用两个中小号的网罗，
