Abstract
We discuss the radar detection method as a probe for high-energy neutrino induced particle cascades in ice. In a previous work we showed that the radar detection techniqe is a promising method to probe the high-energy cosmic neutrino flux above PeV energies. This was done by considering a simplified cascade geometry and scattering model. In this article we discuss the scattering in more detail. We provide a model for the radar cross-section based on the induced plasma properties, and discuss the angular dependence of the scatter.

Summary
In [1], we discussed the radar detection technique as a probe for high-energy neutrino-induced particle cascades in ice. It was shown that if one is able to scatter efficiently, this technique should allow for the cost-efficient detection of neutrino-induced particle cascades above a few PeV. It was shown that if one is able to scatter efficiently, this technique should allow for the cost-efficient detection of neutrino-induced particle cascades above a few PeV It follows that the radar detection method is a promising technique to cover the currently existing sensitivity gap between a few PeV where the IceCube neutrino observatory runs out of statistics [2], and a few EeV where the currently operating Askaryan radio detectors start to gain sensitivity [3, 4]. Having the detailed free charge distribution, the scattering efficiency for layers of equal density will be considered by taking into account for the skin effect. The scattering itself is discussed where it is argued that instead of isotropic scattering a slit-like interference pattern can be expected
