GPR Wave Velocity Estimation Based on the Method of Curves Character and K-Means Clustering

According to the need of ground penetrating radar (GPR) measurement of underground targets, we proposed a new method for the prediction of wave velocity. This method based on radar image curves and K-means clustering algorithm, and we can predict the wave velocity accurately. Proved by the experiment, the calculation precision of this method is higher. Although there are some errors in measurement results, it has good robustness to get it corrected.
