TL;DR: Data from the northern lowlands of Chryse Planitia have revealed a shallowly buried quasi-circular structure about 250 kilometers in diameter that is interpreted to be an impact basin and a planar reflector associated with the basin structure may indicate the presence of a low-loss deposit that is more than 1 kilometer thick.

TL;DR: In this paper, the effect of soil electromagnetic parameters on early-time ground-penetrating radar GPR signals is evaluated in a time interval which contains the direct airwaves and ground waves propagating between transmitting and receiving antennas.

TL;DR: In this article, the authors present a complete range of potential ice types that may occur on these icy satellites to understand how they may affect the results of the proposed missions and select the most suitable data to compute dielectric attenuation, velocity, vertical resolution, and reflection coefficients for such icy moon environments, with the final goal being to estimate the potential capabilities of radar missions as a function of the frequency and temperature ranges of interest for the subsurface sounders.

TL;DR: In this paper, the authors used a capacitive cell (Parallel Plate Capacitor) and a transmission line (Time Domain Reflectometry) to assess the dielectric behavior of solid CO2 (i.e., CO2 ice, snow, powder) and solid CO 2/soil mixtures.

TL;DR: The GPR performance in terms of resolution and maximum penetration depth is evaluated in the considered scenarios for different operating frequencies, thus providing a basic information for the design of systems for future subsurface sounding investigations on Mars.
