GPR Ground Bounce Removal Methods Based on Blind Source Separation

In this paper, the ground bounce (GB) removal methods based on Blind Source Separation (BSS) for land mine detection using ground penetrating radar (GPR) are investigated. These methods include an Independent Component Analysis (ICA) based method and Blind Instantaneous Signal Separation (BISS) based method. First, a modified ICA based method is presented. In this method, a fully automatic eigenimage based Independent Components (ICs) selection strategy combined with a non-homogeneous detector (NHD) is introduced. A BISS based method is also proposed for the GB removal. This method can be applied in various environments as ICA, but it has much fewer number of extracted components than ICA's, but has much fewer number of components to extract, therefore less computation load is required. Experimental results show that the proposed methods exhibit good performance.
