Instantaneous parameters calculation and analysis of impulse ground penetrating radar (GPR) data

We use the wavelet transform (WT) method to analyse impulse GPR signals received from anti-personnel (AP) plastic mines. The mine radar echoes examined in this work are characterized by an average low amplitude and low signal-to-noise ratio (SNR). We focus on the use of WT to extract such weak transients from the noisy background. In particular, we calculate the instantaneous parameters of the radar signals by means of the WT. Instantaneous wavelet power and energy spectra allow enhanced identification of plastic mines echoes in low SNR. We further propose a novel non-linear transform method to process the results after WT in order to increase the energy difference between the mine signal and the clutter
