Detection of Antipersonnel Landmines Buried in the Clay Soil with UWB Impulse GPR

This paper addresses the challenge of detecting and localizing antipersonnel landmines in clay soil using impulse ultra-wideband (UWB) ground-penetrating radar (GPR). The proposed system employs a 1Tx–4Rx antenna configuration and analyzes the spatial-temporal structure of the received signals. The detection approach is based on contrast filtering and a combined indicator that integrates signal energy coefficient and correlation coefficient metrics. Experimental results demonstrate the ability of the system to detect and localize PMN-1 and PMN-4 mines buried in clay soil, highlighting the system’s potential for practical applications in humanitarian demining.
