A clutter suppression method of ground penetrating radar for detecting shallow surface target

GPR for detecting shallow surface target has heavy clutter and target echo cannot be distinguished easily. This paper proposes a PCA-SVD mixed clutter suppression method to realize dimension reduction and reconstruction, which can improve the performance of clutter suppression effectively. SVD processing remove direct wave, firstly. Then PCA remove uncancelled clutter and remove noise. At last, we design an experiment to validate the performance of clutter suppression.
