Description

We develop a drone-borne aerial calibration pulser system for radio observatories for air-showers induced by ultra-high energy (UHE) cosmic rays (CRs) and cosmic neutrinos (CNs). The system is designed to provide a highly practical method for system calibration which transmits high power impulsive radio signals from various locations. We use a solid-state impulse generator and a wide-band bicone antenna with bandwidth of 150-500 MHz attached on a commercial drone. The system is equipped with a differential GPS receiver which provides an accuracy of centimeter level. We implement a high power attenuation shielding box with an extreme light-weight in order to reduce radio interference. In this paper, we report system design, production, laboratory tests, and in-situ performance in TAROGE observatories in Taiwan and Antarctica. Possible applications of this system to next generation radio detectors for UHE CRs and CNs are also discussed.
