This paper presents the Radar for Icy Moon Exploration (RIME) that is a fundamental payload in the Jupiter Icy Moon Explorer (JUICE) mission of the European Space Agency (ESA). RIME is a radar sounder aimed to study the subsurface of Jupiter's icy moons Ganymede, Europa and Callisto. The paper illustrates the main goals of RIME, its architecture and parameters and some recent advances in its design.
The main goal of CONSERT experiment is to reach information on the nucleus of the comet Churyumov-Gerasimenko/67P. In this contribution, we focus on microwave tomography and the study is conducted on an equivalent scaled model of the comet. A simple vectorial-induced current reconstruction algorithm is exploited to obtain qualitative maps of the scene. Imaging results of this test model have been...
This paper presents the Radar for Icy Moons Exploration (RIME) instrument, which has been selected as payload for the JUpiter Icy moons Explorer (JUICE) mission. JUICE is the first Large-class mission chosen as part of the ESA's Cosmic Vision 2015–2025 programme, and is aimed to study Jupiter and to investigate the potentially habitable zones in the Galilean icy satellites. RIME is a radar sounder...
This paper provides an overview of the Europa Jupiter System Mission (EJSM) and of its scientific objectives, focusing the attention on the subsurface radar (SSR) instrument included in the model payload of the Jupiter Ganymede Orbiter (JGO). The SSR instrument is a radar sounder system at low frequency (HF/VHF band) designed to penetrate the surface of Ganymede icy moon of Jupiter for performing...
The 3D FDTD simulation of wave EM propagation in large structures like the cometary nucleus of 67P/Churyumov-Gerasimenko is computationally expensive. With other approximative methods not all propagation phenomena can be sufficiently modeled. We propose to use the PSTD. This method overcomes the computational burdens and memory demands of the FDTD, while it allows accurate modeling of wave propagation...
Low frequency spaceborne radar is a promising opportunity to investigate Earth subsurface in arid and polar areas and for planetary exploration. The radar signal penetrates subsurface and the return signal is the sum of the surface clutter and the subsurface signal that is the signal of interest. In this paper, we describe the simulation of the surface clutter. This signal consists of two parts: electromagnetic...
