Résumé : We discuss the feasibility of the radar detection technique to probe high-energy neutrino-induced particle cascades in ice. The properties of the plasma which is created when a high-energy neutrino-induced particle cascade traverses the medium are modeled in detail for random scattering geometries. This allows us to model the radar scattering cross section for generic cases, where previously our results were based on an empirical thin-wire approximation.
