摘要
利用机载或车载地表穿透合成孔径雷达(GPSAR)可以实现地雷和雷场的远距离大区域快速探测,是探雷的发展趋势.为了降低地雷检测中的虚警,需要基于地雷和杂波电磁特征设计有效的检测器.本文提出了GPSAR浅地表金属地雷二维电磁特征计算方法,理论计算结果与Rail-GPSAR实测数据基本吻合.电磁建模结果表明,浅地表金属地雷图像具有双峰特征,它将有效的提高地雷检测性能.
Air-or vehicle-borne ground penetrating synthetic aperture radar（GPSAR） has the capability to detect landmines and landmine fields over large area from a standoff distance quickly, which is the trend of landmine detection. In order to reduce the false alarms in landmine detection,it is needed the design efficient detector on the electromagnetic characteristics between landmine and clutter. A 2-dimensional electromagnetic signature modeling method of subsurface metallic landmine in GPSAR is proposed whose results fit real data collected by the Rail-GPSAR system. Electromagnetic modeling result shows that the image of subsurface metallic landmine has the two-peak characteristic, which will improve the landmine detection performance greatly.
