During the acquisition of ground penetrating radar (GPR) data, noise would inevitably be mixed in by the influence of external factors, which seriously interferes with the identification and interpretation of effective echo. Therefore, the authors used the bilateral filtering algorithm to remove noise from ground penetrating radar data. By adding White Gaussian Noise to the forward record of ground penetrating radar to simulate the measured ground penetrating radar record, the synthetic record containing noise was filtered by bilateral filter. The results show that the bilateral filtering algorithm can remove most of the White Gaussian Noise, highlight the effective echo information and increase the peak signal-to-noise ratio (PSNR) from 15.845 1 to 22.147 7. Furthermore, the bilateral filter was used to filter the measured records. The filtered results show that the noise removal effect is better, which indicates that the bilateral filter could be effectively applied to the denoise of ground penetrating radar data.
