Abstract

Many countries in the world are contaminated with landmines. Several thousand casualties occur every year. Although there are certain types of mines that can be detected from a safe stand-off position with tools, humanitarian demining is still mostly done by hand. As a new approach, an unmanned aerial system (UAS) equipped with a ground penetrating synthetic aperture radar (GPSAR) was developed, which is used to detect landmines, cluster munition, grenades, and improvised explosive devices (IEDs). The measurement system consists of a multicopter, a total station, an inertial measurement unit (IMU), and a frequency-modulated continuous-wave (FMCW) radar operating from 1 GHz to 4 GHz. The highly accurate localization of the measurement system and the full flexibility of the UAS are used to generate 3D-repeat-pass circular SAR images of buried antipersonnel landmines. In order to demonstrate the functionality of the system, 15 different dummy landmines were buried in a sandbox. The measurement results show the high potential of circular SAR for the detection of minimum metal mines. 11 out of 15 different test objects could be detected unambiguously with cm-level accuracy by examining depth profiles showing the amplitude of the targets response over the processing depth.

圆形合成孔径雷达机载地雷探测实验研究
世界上许多国家都受到地雷的污染。每年有数千人伤亡。虽然有某些类型的地雷可以用工具从安全的对峙位置探测到,但人道主义排雷仍然主要是手工进行的。作为一种新方法,研制了一种配备探地雷达的无人机系统(UAS),用于探测地雷、集束弹药、手榴弹和简易爆炸装置(ied)。测量系统由一架多旋翼飞机、一个全站仪、一个惯性测量单元(IMU)和一个频率从1ghz到4ghz的调频连续波(FMCW)雷达组成。测量系统的高度精确定位和UAS的充分灵活性用于生成埋置杀伤人员地雷的3d重复通道圆形SAR图像。为了演示该系统的功能,在沙盒中埋设了15个不同的假地雷。测量结果表明,圆形SAR在探测最小金属地雷方面具有很高的潜力。通过检查显示目标响应幅度在处理深度上的深度剖面,可以以厘米级精度明确地检测到15个不同测试对象中的11个。
