Radio detection of air-showers has emerged as a powerful technique for high-energy cosmic ray measurements, leading to the development of a new generation of large-scale radio detectors. The Giant Radio Array for Neutrino Detection (GRAND) represents a significant advancement. It is planned as a vast array of wide-band radio antennas spanning an extensive area of 200 000 km2.
To effectively detect air-shower events in such large-scale arrays, an efficient and autonomous trigger system is needed. This presentation introduces a novel multi-level radio trigger, which is crucial for large-scale experiments like GRAND. The first-level trigger identifies potential air-shower signals at the station level. However, the true innovation lies in the second-level trigger operating at the detector level. By evaluating the time-integrated power, it makes reliable event decisions based on the scientific knowledge of radio emissions.
