Coherence factor for rough surface clutter mitigation in forward-looking GPR

We employ a near-field coherence factor for rough surface clutter mitigation in forward-looking ground penetrating radar imagery. The coherence factor is first used to generate a “coherence map” of the region of interest (ROI). Then, a pixel-by-pixel multiplication of a tomographic image of the ROI with the coherence map is performed to generate an enhanced image. Electromagnetic modeled data of shallow buried targets is used to demonstrate the effectiveness of the proposed approach.
