Abstract
Ultra-high energy cosmic rays are expected to produce neutrinos via their interactions with extragalactic photon backgrounds over cosmological distances. I will review cosmic rays and their interactions, how cosmic ray and neutrino interactions produce impulsive radio signals in dense dielectrics, and how we can search for these signals using balloon-borne radio interferometers over the Antarctic ice sheet. I will discuss key results from the four flights of the Antarctic Impulsive Transient Antenna (ANITA) and introduce its successor the Payload for Ultrahigh Energy Observations (PUEO). PUEO is now under construction and currently scheduled for flight in the 2024-2025 austral summer.
