e/Antarctic Impulse Transient Antenna

Information
has gloss	eng: The AA (ANITA) experiment has been designed to study ultra-high-energy (UHE) cosmic neutrinos by detecting the radio pulses emitted by their interacting with the Antarctic ice sheet. This is to be accomplished using an array of 36 radio antennas (cylindrically arranged with an approximate radius of 3m and a height of 5m) suspended from a helium balloon flying at a height of about 35,000 meters.
