Description
Several balloon-borne radio experiments have targeted the detection of ultra-high energy neutrinos interacting near the Earth's surface. Radio pulses produced by cosmic ray air showers constitute a relevant class of events among the recorded signals. Cosmic ray signals can be produced either by downward-going air showers, where the signal reflects off the Earth's surface before reaching the payload; or by atmosphere-skimming air showers, that reach the detector directly. In this work, we discuss an update of simulation-based energy estimation methods for reflected events, as well as an adaptation of this method to atmosphere-skimming events. The performance of the method is evaluated in different scenarios of angular resolution, primary mass and environmental noise.
