Multiple landmine detection algorithm using ground penetrating radar

This paper introduces a multiple landmine extraction algorithm from the data which are obtained from the ground penetrating radar (GPR). Conventional algorithms focus on extracting a single landmine. The landmine, however, is not buried under the ground alone in the real cases; it is buried with stones or other landmines. Therefore, detection of multiple landmines is an important problem. The proposed algorithm is composed of two steps. The first step finds the number of buried landmines using the energy projection method. The second step extracts individual buried objects from the data that have multiple landmines using the symmetric filtering method. The experiments show that the proposed algorithm demonstrates the potential of detecting multiple landmines.
