Abstract

Cleaning of contaminated lands containing unexploded ordnance (UXO) and mine fields demands special consideration in the war-torn countries. Some geophysical methods have been used for detecting these destructive remnants of war. Nowadays, Airborne GPR has been considered as a fast and effective tool for UXO Detection. In this study, the feasibility of Airborne GPR for Detection of anti-personal metallic landmines has been investigated by Numerical Simulation of back scattered GPR waves from two artificial physical models A and B. Model A is a column of a two-layer model comprising of a layer of soil under a layer of air. In model B, an anti-personal metallic landmine has been buried in the center of model A at a depth of 10 cm beneath the soil. By using the numerical finite-difference time-domain (FDTD) method, the radargram and central traces of back scattered GPR waves from both physical models A and B have been simulated in various altitudes (0-10 meters) and operating frequencies of the transmitted GPR wave (100-1500 MHz). To do this, MATLAB and REFLEXW software packages have been employed. Moreover, several signal processing techniques including Signal Energy analysis, multi resolution Wavelet Transform, and Time-Frequency Analysis have been performed instead of using the noise removal and trace extraction, which are related to the target. As a result, Detection of intended mine becomes possible by applying Airborne GPR up to altitude of 10 m and using operation frequency of transmitted GPR wave of 550 MHz to over 1000 MHz.
