Abstract
In order to reduce the interference of multiple echoes from water and metal on detection effect of ground penetrating radar (GPR), an improved predictive deconvolution has been proposed based on wavelet analysis (short for PDWA method). The PDWA method firstly decomposes the GPR signals into time domain sub-signals with different scales by wavelet analysis, and then filters the time domain sub-signals by predictive deconvolution and wavelet threshold denoising, at last reconstructs the filtered sub-signals to obtain the analysis result. Processing detection signal of model experiment by the PDWA method, the result shows that, comparing with predictive deconvolution, the PDWA method can suppress multiple echo interference, identify the target reflection accurately, and enhance the signal to interference ratio (SIR) of target reflection, thereby improving the detection resolution and the accuracy of image analysis of GPR signals.
