GPR attenuation varies along the path because the wave interacts with different subsurface conditions as it travels. Factors like material properties (dielectric constant, conductivity), frequency-dependent loss, layering, and interfaces cause energy to fade at different rates in different segments. Higher frequencies attenuate more quickly, scattering and reflections at boundaries add irregularities, and moisture or soil changes alter how the signal propagates. All of this leads to non-uniform dissipation with distance, so the description that the GPR signal dissipates in a non-uniform way with distance best matches how GPR behaves in real environments. The idea that attenuation would be uniform, dissipate completely only at short range, or stay constant with distance doesn’t reflect these varying influences along the path.
