“…Deep interior structure tomography requires a low frequency radar (LFR) in order to propagate through the entire body and to characterize the deep interior. The HFR design is based on the WISDOM radar [23,24] developed for the ExoMars / ESA-Roskosmos mission and LFR is a direct heritage of the CONSERT radar designed for ESA's Rosetta mission.…”

IntroductionAt the inception of a new mission concept, the system design of a spacecraft (planetary robots included) is a critical phase that should not be overlooked. Galvanized by the prospects of an exciting concept, it is often tempting to delve too quickly into subsystem design, at the peril of the mission and its development team. Identification of key links, interactions, and ramifications of design decisions are crucial to the feasibility of the concept and success of the mission. Only then can the optimized system design be found, which may not be the sum of the optimized subsystems.Building on a comprehensive review of existing and future planetary robotic missions, this chapter uses the system engineering design philosophy and discusses the mission-driven design considerations, the system-level design drivers as well as the subsystem design trade-offs for a robotic system, whether the mission is set to explore the lunar craters, the Martian landscape, or beyond. It demonstrates the design thought process starting from the mission concept up to the baseline design at the system and subsystem levels. As a result, the chapter offers a number of system design tools as the foundation or integrator for technologies discussed in subsequent chapters.The chapter is structured systematically as follows:• Section 2.2: This section describes in detail the system design approach and implementation steps applicable to planetary robotic missions and required robotic systems. The process starts from defining the mission scenario, which provides inputs for system-level functional analysis and determination of functional objectives for the robot(s). This then allows the progression to the next phase of the system definition by specifying and reviewing design requirements (e.g., using the S.M.A.R.T. method). Design drivers are subsequently identified and used to evaluate and trade-off different design choices, which results in the baseline design.

“…Presently, a ground‐based radar system is planned for the 2018 ESA–NASA rover mission (formerly ESA's ExoMars mission). The WISDOM (Water Ice and Subsurface Formation Observations on Mars) radar system will operate at 500 MHz to 3 GHz with cross‐polarimetric capabilities [ Hamran et al , 2007; Plettemeier et al , 2009]. As the rover may also be equipped with a drill capable of retrieving 2 m cores, the potential exists for the validation of radar surveys with core analyses.…”

[1] Exploration of the polar ice caps and apparent glacial and periglacial landforms on Mars will aid our understanding of its ancient climate conditions and the history of water on the planet. Given that ground-penetrating radar (GPR) is likely to be used to understand these features, we investigated the real component of the complex dielectric permittivity of stratified segregation ice, non-stratified segregation ice, and polygonal ice wedge deposits in the Canadian Arctic. We acquired moveout profiles with a 450 MHz GPR on ground ice formations that had active layer sediments excavated prior to surveying. Using ice core data collected from these sites, we found that the volumetric fraction of ice plays the greatest role in defining the dielectric permittivity of the deposit and that it can be described using a modified complex refractive index method (CRIM) dielectric mixing model. Using the modified CRIM model, we estimate the dielectric permittivity of several ground ice deposits on Earth and present further estimates for similar features on Mars using permittivity values for Martian sediments derived from both theory and laboratory methods.
