We discuss the feasibility of the radar detection technique to probe high-energy neutrino induced particle cascades in ice. The properties of the plasma induced 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, where previously our results were based on an empirical thin-wire approximation. Using this improved model, we present the sensitivity for the radar detection technique to probe high-energy cosmic neutrinos in the PeV-EeV region. It is shown that the promising sensitivity is crucially dependent on several up to now unknown plasma parameters such as its lifetime and free charge collision rate, which have to be determined experimentally.
