Extended Data Fig. 8: Comparison between the observed ground-penetrating radar (GPR) data and synthetic data.
From: Layered subsurface in Utopia Basin of Mars revealed by Zhurong rover radar
a, Part of the Rover Penetrating Radar (RoPeR) low-frequency data (track distance from 320–420 m). b, The corresponding normalized average strength envelope of a. c, Simulated low-frequency radar data using the model shown in Extended Data Fig. 7. d, The corresponding normalized average strength envelope of c. The peak amplitudes of the strength envelope in d were clipped by 20% to boost the deep record. Both datasets were processed with the same processing procedures as those shown in Extended Data Figs. 2 and 3.
