Compositional variations along the route of Chang’e-3 Yutu rover revealed by the lunar penetrating radar

Progress in Earth and Planetary Science, 2020
Using the high-frequency lunar penetrating radar data obtained by the Chang’e-3 mission, we apply the frequency-shift method to calculate the decay rate of the electromagnetic wave in the regolith-like ejecta deposits of the Ziwei crater.
