俄歇工程无线电阵列的数据采集、触发和滤波

Data Acquisition, Triggering, and Filtering at the Auger Engineering Radio Array

J. L. Kelley

摘要:

俄歇工程射电阵列(AERA)目前正在皮埃尔俄歇天文台探测能量在10^17 eV及以上的宇宙射线,方法是触发相关空气簇射产生的射电辐射。无线电探测技术必须应付人为无线电频率干扰的显著背景,但可以提供关于具有高占空比的簇射发展的信息。我们讨论了我们的技术,以处理在低功耗的自主阵列,包括触发和滤波算法,数据采集设计和通信系统的自触发无线电检测的挑战。

英文摘要:

The Auger Engineering Radio Array (AERA) is currently detecting cosmic rays of energies at and above 10^17 eV at the Pierre Auger Observatory, by triggering on the radio emission produced in the associated air showers. The radio-detection technique must cope with a significant background of man-made radio-frequency interference, but can provide information on shower development with a high duty cycle. We discuss our techniques to handle the challenges of self-triggered radio detection in a low-power autonomous array, including triggering and filtering algorithms, data acquisition design, and communication systems.
