Abstract:
The Chang'e-4 (CE4) mission is performing the first ground penetrating
radar (GPR) measurements on the far side of the Moon
to study the subsurface structure and geological evolution of
the Von Kármán crater. In their Article, Zhang et al. interpret a
series of reflectors in the low-frequency radar data in terms of a
complex stratigraphy formed by different ejecta deposits coming
from nearby craters. Here we show that these reflectors are instead
artefacts generated by the system design and antenna configuration.
This problem could also affect future data collected by the
CE4 low-frequency system as well as by other missions that use a
similar radar design, such as the one onboard the rover of the
Martian Tianwen-1 mission.
