On Improving Subspace Spectral Feature Technique for the Detection of Weak Scattering Plastic Antitank Landmines

摘要

The detection of weak scattering plastic landmines using ground penetrating radar (GPR) is a challenging task. This paper presents a few enhancements to the previously proposed subspace spectral correlation feature (SCF) to improve the detection of weak scattering plastic landmines. Preliminary results indicate that the improved subspace SCF technique is able to reduce the false alarm rate by 28% compared to the original subspace SCF at 90% probability of detection, in a data collection obtained from three different test sites that contains about 460 weak-scattering plastic anti-tank landmines. Fusion results with edge histogram descriptor (EHD) confirm the performance improvement resulted from enhanced subspace SCF.
