Performance of a demining GPR related to soil properties and clutter

GPR is about to be used in the landmine clearance operations and the performance has to be evaluated in such safety critical applications. In order to study the influence of heterogeneity on GPR performance, three types of soil were investigated. GPR clutter was modeled from the estimated heterogeneity to see the difficulty to GPR. A dual sensor system that combines metal detector and GPR was tested on these three types of soil to evaluate the performance for demining. The GPR performance obtained in the test showed a clear correlation to GPR clutter, and thus the study demonstrates that clutter plays major role to detect a small object in a heterogeneous soil by GPR.
