Landmine detection is a difficult and very sensitive task as it may cost a human life even with a slight mistake or misdetection. In addition, the invention of non-metallic landmines made the scenario much more complicated and difficult. Various landmine detection techniques have been proposed, such as a metal detector, an electromagnetic induction (EMI), and so on. However, the probability of false alarm is very high in such techniques, which is considered as a sever problem. In this paper, ground penetrating radar, which has the capability to detect the non metal and the plastic mines, has been proposed to detect landmines. In addition, super resolution technique MUSIC algorithm and SAR (Synthetic Aperture Radar) has been implemented for the signal processing and image reconstruction of a GPR signal.
