Data set generation and inversion simulation of radio waves propagating through a two‐dimensional comet nucleus (CONSERT experiment)

To prepare the Comet Nucleus Sounding Experiment using Radio wave Transmission during the Rosetta mission, we study the electromagnetic wave propagation through a comet nucleus model and tomographic inversion in a two‐dimensional setting. For the propagation, the Ray Tracing Method (RTM) is validated with respect to the Pseudo‐Spectral Time Domain (PSTD) method. For the inverse problem, a Tikhonov‐like inverse RTM method based on weak permittivity assumptions is used, with synthetic data derived from the PSTD algorithm. Reconstruction results show that the Consert data will permit a reliable tomography of the comet nucleus. Surface data will enhance the quality of the imaging.
