Abstract :
Ye and Jin presented a method to derive the soil dielectric permittivity from radar surface echoes when a Digital Elevation Model of the observed region is known. However, this method has been already extensively applied on Mars, and the scientific protocol to demonstrate its efficiency only derives the numerical uncertainties inherent to the simulation tool used by the authors.
