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以上的宇宙射线，通过触发在相关的空气簇射产生的无线电发射。无线电探测技术必须科普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。
Abstract 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.
