自第二次世界大战以来，杀伤地雷一直被滥用，它们在地面的长期存在给许多国家的发展造成障碍，并迫使人民生活在不断的恐惧之中。越来越需要可靠的地雷探测和定位系统，使受影响地区恢复正常使用。由于探地雷达（GPR）具有探测金属和非金属物体的能力，因此它是探测地雷的一种有意义的方法，可以使行动更快、更安全。与普通杂波物体不同，大多数地雷可以建模为多层介电柱体，引起多次干涉反射，并产生具有特征角图的特征。因此，预计地雷产生的信号具有一些可用于降低探地雷达误报率的区别特征。在这项研究中，对三种惰性地雷进行了测量，以研究和表征地雷特征作为偏振角和纵横角的函数。
Antipersonnel landmines have been indiscriminately used since World War II, and their long-term persistence in the ground creates a barrier to development in a large number of countries and forces people to live in constant fear. There is a growing demand for reliable landmine detection and localisation systems to return affected areas to their normal use. Due to its ability of detecting both metallic and non-metallic objects, ground penetrating radar (GPR) is a meaningful method for detecting landmines that may allow faster and safer operations. Unlike common clutter objects, most landmines can be modelled as multiple layered dielectric cylinders that cause multiple interfering reflections and result in features with a characteristic angular pattern. Due to this, landmines are expected to produce signatures that present some discriminant features that could be used for reducing the GPR false alarm rate. In this study, measurements of three inert landmines have been carried out to study and characterise landmine signatures as a function of polarisation angle and aspect angle.
