Fuzzy weighted background removal is applied to the data through a sliding window and then target energy functions are obtained by means of convolution summations of consecutive A-scan signals in an appropriate manner. An auxiliary detection function is proposed as an emphasized detection test statistic and then an automatic detection warning signal creation method is devised. The proposed method has been tested over a set of small-sized surrogate anti-personnel AP mines which are not easily detectable and medium-sized surrogate AP and Anti-tank mines. The results are promising as nearly full detection performance. Zero false alarm rate is achieved in this dataset without remarkable corruption in estimated target GPR images. Moreover it is observed that the noise immunity of the proposed method is highly satisfactory in terms of detection probability. 1. Introduction Ground penetrating radar GPR is used in a broad range of applications related to underground inspection problems 1 . Buried pipes cables mines unexploded ordnances or ancient remains can be found using GPR. In this context the objectives can be the obtaining of a detection warning signal DWS along the scanning path 2D depth imaging of the scanning line or 3D imaging of the suspicious region in both depth and moving direction. Identification processes 2-7 can be applied after the buried object location is determined. There are numerous methods to detect buried objects .
