Clutter reduction techniques of ground penetrating radar for detecting subsurface explosive objects

Ground Penetrating Radar (GPR) is a method based on propagation of electromagnetic waves to detect shallowly buried objects and also gives the depth of buried objects. The land mines are made out of plastic and less metallic. Without signal processing it is difficult to detect these explosive objects using GPR. The presence of clutter makes GPR-based landmine detection difficult. Most contributions in this area deal with clutter reduction techniques. There are many signal processing techniques in the literature that have been successfully applied to GPR data for the detection of subsurface explosive objects. This paper covers various Clutter reduction techniques along with results and comparison with respect to SNR (Signal to Noise Ratio) and ROC (Receiver Operating Characteristic) curves.
