Modeling of near-surface structure and Response simulation of GPR in the Jezero crater, Mars

Abstract

NASA’s upcoming Mars 2020 will carry Ground Penetrating Radar (GPR) named RIMFAX to Mars for exploration. Mars 2020 will land at Jezero crater, located to the northwest of the Isidis basin. The landing site experienced series of geological processes such as delta formation, lavas coverage and surface weathering. Establishing the electromagnetic model here, which is used for forward simulation of RIMFAX will help the later data processing and interpretation. This paper considers the interface fluctuations, the randomness of the background medium, and the randomness of the cracks to establish a Mars near-surface electrical model, and performs forward result based on the parameters of RIMFAX. The research will support the later data processing and interpretation.
