Therefore, clutter suppression is the key step in ground penetrating radar signal processing. In this paper, Principal Component Analysis (PCA) algorithm is used to suppress GPR clutter. First, mean filter metho
Short-time Fourier transform (STFT)-based methods [13,14] may be applied for clutter suppression, using the STFT to represents the energy in a particular windowed signal as a set of point estimates on the time-frequency lattice; the time-frequency reassignment is then used to shift these ...

Such methods may be employed with coils on either side of (or both sides of) a programmed magnet. Although magnetizable material (e.g., of programmed magnet 1402) is shown in FIGS. 14A and 14B to be round, one skilled in the art will recognize that different shapes of magnetizable ...

In order to suppress or eliminate the interference of the roadway wall clutter, this paper presents a clutter suppression algorithm based on Kalman filter model and SVM. In this method, the Kalman filter model suitable for the underground environment is constructed. The clutter estimation and the ...
